¿Quieres mostrar las miniaturas de tus entradas en tus feeds RSS de WordPress?
Los feeds RSS le ayudan a promocionar su contenido en directorios, lectores de feeds y otras aplicaciones que utilizan feeds RSS. Sin embargo, la triste realidad es que las imágenes características de las entradas de su blog no aparecerán en sus feeds RSS.
En este artículo, le mostraremos cómo puede añadir miniaturas de entradas a sus feeds RSS de WordPress.
¿Qué es el feed RSS de WordPress?
RSS, o Really Simple Syndication, permite a usuarios y aplicaciones recibir actualizaciones periódicas de un sitio web o un blog en un feed web.
Los feedsRSS te ayudan a obtener actualizaciones de los sitios web que elijas sin tener que visitarlos manualmente. Te ayuda a guardar o ahorrar tiempo, y puedes ver el contenido más reciente en tu correo electrónico, lectores de feeds y otros dispositivos.
Si tiene un blog en WordPress, los feeds RSS pueden ayudarle a promocionar sus contenidos y atraer tráfico a su blog. Puedes hacer que los lectores encuentren fácilmente nuevos artículos y hacer que vuelvan a tu sitio para ver contenido nuevo.
Sin embargo, el problema de los feeds RSS de WordPress es que no muestran las imágenes destacadas de las entradas de tu blog.
Añadir miniaturas de entradas ayuda a personalizar el feed RSS. También ayuda a mejorar el feed y proporcionar una mejor experiencia de usuario.
Dicho esto, veamos cómo añadir miniaturas de entradas a los feeds RSS de WordPress. Le mostraremos dos maneras de hacerlo, incluyendo el uso de un plugin de WordPress y la adición de una función simple a los archivos de su tema.
Cómo añadir miniaturas de entradas a feeds RSS usando un plugin (de forma sencilla)
La forma más sencilla de mostrar imágenes destacadas en el feed RSS es utilizar el plugin Featured Images in RSS for Mailchimp & More (Imágenes destacadas en RSS para Mailchimp y más).
Es un plugin gratuito de WordPress que te ayuda a añadir imágenes a tu feed RSS para que se muestren en tus campañas de correo electrónico RSS y en cualquier otro lugar donde se utilice tu feed RSS.
En primer lugar, tendrás que instalar y activar el plugin. Si necesitas ayuda, consulta nuestra guía sobre cómo instalar un plugin de WordPress.
Una vez activado, puede dirigirse a Imágenes destacadas en RSS desde su escritorio de WordPress.
El plugin te permite cambiar el tamaño de la imagen RSS, la alineación, el relleno del texto y elegir si quieres que se pueda hacer clic en las imágenes.
Cuando hayas realizado los cambios deseados, no olvides hacer clic en el botón “Guardar cambios”.
Añadir manualmente miniaturas de entradas a feeds RSS (código obligatorio)
Otra forma de mostrar miniaturas de entradas en los feeds RSS de WordPress es añadir un fragmento de código al archivo function. php de su tema.
Sin embargo, no recomendamos editar directamente el archivo functions.php, ya que el más mínimo error puede romper tu sitio WordPress. En su lugar, una forma más fácil de añadir código es utilizar el plugin WPCode.
Con WPCode, puedes añadir fragmentos de código en WordPress de forma segura y sin errores. Además, te permite mantener tu código personalizado incluso si actualizas o cambias tu tema de WordPress.
La versión gratuita de WPCode viene con todo lo necesario para añadir código personalizado en WordPress, incluida una biblioteca de fragmentos de código listos para usar. WPCode Pro incluye características avanzadas como revisiones de código, fragmentos de código programados, píxeles de conversión y mucho más.
En primer lugar, tendrás que instalar y activar el plugin WPCode. Puedes seguir nuestro tutorial sobre cómo instalar un plugin de WordPress.
Una vez que el plugin esté activado, puedes ir a Fragmentos de código ” + Añadir fragmento desde el escritorio de WordPress. A continuación, vaya a la opción “Añadir su código personalizado (nuevo fragmento)” y haga clic en el botón “Usar fragmento”.
Después, tienes que copiar el siguiente código:
function rss_post_thumbnail($content) {
global $post;
if(has_post_thumbnail($post->ID)) {
$content = '<p>' . get_the_post_thumbnail($post->ID) .
'</p>' . get_the_content();
}
return $content;
}
add_filter('the_excerpt_rss', 'rss_post_thumbnail');
add_filter('the_content_feed', 'rss_post_thumbnail');
A continuación, dale un título a tu fragmento de código. A continuación, pega el código que has copiado antes en el cuadro “Vista previa del código”.
No olvide seleccionar “Fragmento de código PHP” como tipo de código en la lista desplegable de la derecha.
A continuación, desplácese hasta la sección “Inserción”.
Para este fragmento de código, deberá dejar seleccionada la opción “Insertar automáticamente” para insertar y ejecutar automáticamente el fragmento de código en su sitio.
Por último, activa el conmutador de “Inactivo” a “Activo”.
A continuación, no olvide pulsar el botón “Guardar fragmento de código”.

Hello,
When I added this code to my functions.php, it changed the length of the description. Now all the blog post content is showing in the RSS feed. Before it was cut off. Is there a way to limit the description to a max of 300 words?
Thank you
WPBeginner Support says
For what you are wanting you would want to change get_the_content to get_the_excerpt and that should allow it to display with the excerpt

First of all let me thank you guys for various tutorials that have helped me over the time to fix several issues.
I am just looking for a simple implementation.
I just want my WordPress Category Feed e.g. wpbeginner.com/category/wp-tutorials/feed to have post featured image.
So that under category/news/feed my articles show featured images in Google News Publishers sections.
WPBeginner Support says
The method from our guide above should allow you to add images to your RSS feeds. The plugin has a paid plan if you wanted to specifically exclude other categories.

Jana says
This does not work. Unfortunately, when executed it displays the full post content and the full-size featured image instead of the excerpt.
WPBeginner Support says
From your statement it does work. It adds the post thumbnail which is what this tutorial is about, you would want to change the get_the_content to get_the_excerpt to show the excerpt and not the full content.

So how do you modify the function if you are using an ACF for your main custom thumbnail instead of the wordpress thumbnail?
Dani Serrano says
Hi all,
I have 4 CPT in my site.
Added all of them in my feed following: https://www.wpbeginner.com/wp-tutorials/how-to-add-custom-post-types-to-your-main-wordpress-rss-feed/
But now I want to add the thumbnail as content into feed.
Do you know how I can do it?
That I need is similar to this post content but for all CPTs.
Thanks and Regards,
Dani

Sir. I am using the RSS feeds of other websites to pick the news but it doesn’t show the feature images just only show the link. Will this code or plugin work for me?? I tried both but nothing happened. Thanks.
And please suggest me what should I do
SoNyne says
So this just adds the image to the content. Not really desired for my needs. How can I add a new field so that I can use get_thumbnail when using the fetch_feed method in WordPress?

Hello, how can I apply this filter in a custom rss
I have the following rss created
add_action(‘init’, ‘customRSS’);
function customRSS(){
add_feed(‘feedname’, ‘customRSSFunc’);
}
function customRSSFunc(){
get_template_part(‘rss’, ‘feedname’);
}
Great job
Steffi says
I pasted the code in WP functions now, my side is crashed. White screen. Can not log in. HELPPP!!!!
WPBeginner Support says
You will need to connect to your website using an FTP client. Then locate the functions.php file (you will find it in /wp-content/themes/your-theme-folder/), edit the file using a plain text editor like Notepad. Undo the changes you made earlier. Finally, save the file and upload it back.

I tried same for my site but rss feed not showing images,plz help
WPBeginner Support says
RSS feed is an XML file. Usually when you are viewing an XML file in a browser it will only show you the code and will not execute the markup. You need to check your feed into a feed reader like Feedly.

Is it possible to use this function with the WP RSS WIdget? I need to imports POSTs with thumbnails to another site.
Suresh Khanal says
It was really a headache to see the RSS-to-email campaigns without no images because the RSS feed did not have the necessary tag to pull images from. Anyway, changed the functions.php file and now MailChimp can pull the required components and now the emails look beautiful.
However, still the images in RSS feed look really big and wish to resize them to a suitable size. Needs to search more and find a solution for this.
Elodie says
Thank you it crashed my site!
Jeremy R. Hammond says
This accomplished getting the thumbnail included in the feed, but created two other problems:
1) My feed now shows the full content instead of just the summary.
2) The feed is also capturing my featured image from the content (the full image, not just the thumbnail) and this shortcode:
[caption id="attachment_24496" align="aligncenter"width="739"]Caption Text[/caption]
I assume there’s a way to correct both of these problems. Can anyone assist?
Gretchen Louise says
Thank you so much for this code! Any suggestions for editing it so that the post thumbnail is a link to the post itself?
Keifer Moore says
I tried to implement this and received “Parse error: syntax error, unexpected ‘<' in /home/content/98/8201898/html/wp-content/themes/twentyfourteen/functions.php on line 526"
I can't access wp-admin or the rss feed. I've tried making new wp-config.php files and nothing's working. Could someone help?
Salvatore Capolupo says
Great help, thank you
I Plank says
thanx a lot. it works
Benjamin says
Hi whoever wrote this post. Thanks at first, but when using this code, my feed displays the image in FULL SIZE, not as a thumbnail. What would you recommend to define a size?

Hello,
Thanks you for sharing this!
I’d like to know if this is possible (and how) to use this script to display author image in rss feed? Is there a way to do this ?
Thanks

Why we need check has_post_thumbnail()?
get_the_post_thumbnail() return empty string if it couldn’t get thumbnail. Also, no need to define global $post. Filters calling from inside the loop.
And why we call get_the_content(), is it nessesary?
This code will enaugh:
—
function rss_post_thumbnail( $content ){
$img = get_the_post_thumbnail( null, array(100, 80), array( ‘align’ => ‘left’, ‘style’ => ‘margin-right:15px;’ ) );
$content = $img . $content;
return $content;
}
add_filter( ‘the_excerpt_rss’, ‘rss_post_thumbnail’ );
add_filter( ‘the_content_feed’, ‘rss_post_thumbnail’ );

Sorry for my english. It’s not my native.

Hello sir, I have added code on functions.php but thumbnail not showing
Brett Bumeter says
Trying this with the genesis magazine theme, no luck. The article is getting a wee bit dated. I was wondering if something might have changed in wordpress since this was originally written, or if maybe I’m just missing something. Been a while since I wondered down the rabbit hole chasing feed code
/** Add thumbnail to Magazine theme feed*/
function rss_post_thumbnail($content) {
global $post;
if(has_post_thumbnail($post->ID)) {
$content = ” . ‘ID).'”>’. get_the_post_thumbnail($post->ID).’‘ .
” . /* full content option get_the_content() */get_the_excerpt();/*exercpt option */
}
return $content;
}
add_filter(‘the_excerpt_rss’, ‘rss_post_thumbnail’);
add_filter(‘the_content_feed’, ‘rss_post_thumbnail’);
Editorial Staff says
Just tested the code from the article on a custom genesis child theme. It works fine. It won’t work with the default WordPress feed that firefox shows. But if you go to the atom feed, then it will work. If you are using a feedburner or another app, it should work.

Nick Aster says
Ok…. wait a minute.
Looks like this forces my RSS feed to be full content. Is that the case?
More importantly, it looks like all this does is slap the tumbnail at the beginning of the content in the RSS feed. Am I missing something here?
Editorial Staff says
Yes, it does make the feed full content. You can change get_the_content() to get_the_excerpt().
Yes, the point is to add the featured thumbnail in RSS. In most cases, that is added before the post. You can style the paragraph tag however you like. Add a float:left; or anything that you want.

Hi i tried this but it gives error Fatal error: Call to undefined function add_filter() in wp-includes/functions.php on line 33 . please help me to solve this porblem. thanx in advance.
AndyiBM says
This works great, except that when there is a thumbnail present, the feed always repeats the post title within the content text (or excerpt text, as I’m using), which looks a little redundant. For posts without a thumbnail, the title is not repeated. Is there any way of removing this extra title text? It has no surrounding tags, so I can’t hide it using CSS.
Piotr Sajnog says
Is there anyway to align post thumbnails to the left of the entry in RSS feed?
Editorial Staff says
Yes, add styling to it. Change the Paragraph tag into a Div and tell it to float left with some margin.

AzzePis says
I think it’s better if you change code:
$content=”.get_the_post_thumbnail($post->ID).”.$content;
to maintain the original content.
Meg says
so what would the final code – all of it – look like?
Non-coder who wants a thumbnail in her blog feed.
Editorial Staff says
The code in the article is the final code that you need… ofcourse if your theme doesn’t have thumbnail enabled, then you will need more.
Administrador
Cosmin says
How would you make the post thumbnail link from RSS to the post?
I don’t get along with PHP, any help is appreciated
Editorial Staff says
You would modify the function a little bit. Add this php code in the link tag: the_permalink($post->ID)

This is really something! I would love to add something like this to Inside the Webb, I’ll have to mess around with some code and see what I can do.
