Learn why your WordPress RSS feeds are important and how you can enrich your RSS feeds by adding featured images from your posts.
RSS feed of your WordPress blog is required for several popular applications and services around the web.
If you want to promote your blog in directories, feed readers, and other similar services, you still need to make use of your RSS feed. The problem with default WordPress RSS feed, however, is that it doesn’t include tags for your featured images.
You might have set your best image for a post as a featured image and it can be sad not to have that featured image appear in your RSS feeds.
Your feeds might look okay if you publish feeds with full text as you have other media files within your post. But if you only publish the Summary in your feeds, by default your feeds looks plain and do not include tags for an important visual element such as images.
Enriching your WordPress RSS feed to include featured images can help in improving your website’s presence significantly on necessary applications and services.
First, let me take some time to discuss what are RSS feeds in WordPress and why adding images to your WordPress RSS feed might be significant. If you want, you can directly skip to the set of instructions below.

Introducing WordPress Feeds
I assume you mostly know about feeds and syndication if you are reading this topic, but let me briefly introduce it in the context of WordPress.
Feed is a data format that allows you to keep track of new content on websites (that enable and publish such feeds). There are different types of feeds, such as RSS and Atom Formatted feeds. RSS (or Really Simple Syndication feed formats) are the most common ones among them.
WordPress has some built-in feeds by default, mostly for content and comments. All our WordPress powered websites come with a default feed template as part of the core files.
While four templates (feed-rss2.php, feed-rss.php, feed-rdf.php, and feed-atom.php) display post entries, two other core templates (feed-atom-comments.php and feed-rss2-comments.php) display comments in atom and RSS formats.
Those basic templates can be customised to meet your further needs.
Instead of going into depth on the topics of feeds here, I recommend reading the detailed codex article if you want to learn more about WordPress Feeds.
Publishing Feeds in WordPress
You can choose to publish Summary text feeds or Full feeds for your posts in WordPress. You can define these settings by navigating to Settings > Reading page. See the screenshot below where I have set to show only the summaries for my posts.
Why Add Images to your RSS Feed?
There might be several reasons why you want to customise and enhance your RSS feed by adding images.
I recently encountered few applications of RSS feeds, which, in fact, inspired me to come up with this post. These examples might also clarify your need to consider adding featured images in your WordPress RSS feed.
- Setting up RSS driven campaign in MailChimp, which requires image tags in your feed if you want to show images in the email campaigns. (Learn how to setup a RSS driven campaign in MailChimp here)
- Feed readers such as Feedly, Flipboard that uses your feed to pull in images for the post.
- Feed reading desktop applications such as RSS Owl, FeedReader etc.
- Showing images alongside news/blogs if your website or blog appears in Google News.
Is RSS Dead?
Before we move on, one more topic that I want to mention briefly is this ongoing ‘RSS is dead’ discussion.
I agree that RSS feed might not be popular as in past, but it’s certainly not dead.
With discontinuity of popular Google RSS reader, you might have come to believe that RSS is dead for sure.
But the fact is that RSS is not dead already! At least not as of now!
There are people who still love RSS and the rise of several other RSS reading services help support my claim. Feedly, for example, is arguably the most popular RSS feed reader and the service saw 900% growth from 2013-2105.
My other favourite social media application Buffer also offers to integrate RSS feed to import posts that can be then published on social media channels.
So there’re plenty of feed reader websites and applications that make use of RSS feeds.
If you are now convinced that RSS feeds still matter, here’s how you can enrich your feeds by automatically adding the featured images of your posts.
Plugins to Add Featured Image in WordPress RSS Feed
Few years back, I wrote a post suggesting how to display images in RSS feeds adding a custom code to your functions.php file. The method doesn’t work for all blogs, and I do not recommend editing your functions.php file (unless you know what you are doing).
Instead, let me recommend you few plugins that can easily help you achieve this feature.
1. Featured Images in RSS
Featured Images in RSS is one of the most used plugins to add this feature in WordPress. Available from the WordPress repository for free, this plugin lets you add featured images in your website's RSS feed.
Unlike other similar plugins available on WordPress repository, this plugin comes with additional easy size and positioning options for your featured images.
- Install the Plugin Featured Images in RSS w/ Size and Position.
- Once activated, go to Settings > Featured Images In RSS Feeds to change the settings of the plugin.
- You can then choose the featured image size to be displayed in your RSS feeds. It lets you choose from all the image sizes that you have defined in your Media options.
- You can also choose how you want the featured images to appear in the feeds. You can define the positioning of the featured images from the options including left, right, or centre in your RSS feeds.
See the screenshot below to see how WPism’s feed looks after adding images in centre above the feed.
2. Send Images to RSS
Send Images to RSS plugin is one of the recent plugins with lots of features related to Images and RSS. The plugin is frequently updated and solves several problems with Images in your RSS feeds.
This plugin mainly helps you to optimize your images if you are publishing Full Text RSS Feeds. It makes your feed images smaller and email friendly adding markup, which email clients can handle.
As of the latest version, however, the plugin has also added options for Summary Text Feeds. The plugin can now add your post's featured image automatically to your excerpt. You can also choose the size and alignment of the image and if no featured image is set, the plugin will use the first image uploaded to the post.
- Install the Plugin Send Images to RSS.
- Once activated, go to Settings > Send Images to RSS to configure your settings.
- To use the featured image in RSS feed, find the “featured Image Size” option under summary settings as seen below.
The best thing about the plugin is that it allows you to choose an appropriate image size to work with popular Mailchimp and also set a custom excerpt length.
3. Featured Image In RSS Feed
Plugin Featured Image In RSS Feed simply adds the featured image to your RSS feed. This plugin has been recently updated to support custom image sizes.
Available for free on plugin directory, Featured Image In RSS is actively used by more than 4000+ at the time of writing this post.
- Install the Plugin Featured Image In RSS Feed.
- Once activated, go to Settings > Image In RSS Feed to change your settings for featured image size (see the screenshot below).
Manual – Add Code for Featured Image
If you are comfortable editing your theme files (I strongly recommend using child theme), use the instructions below to add featured image to your RSS feeds with few lines of code.
Please make a backup of your files before you make any edits.
- Navigate to your theme editor (Appearance > Editor).
- Select and open the “functions.php” of your WordPress theme you have activated.(Remember to make edits only to your child theme).
- Add the following line of codes to the file.
Link to Gist on Github
– That’s all you need to do! You should now see thumbnails in your feeds!
Confirming Images in Feeds
Once you have used the above plugins, you might want to confirm if your feeds now include images.
As browsers like chrome don’t automatically display feed visually, it might be difficult for you to verify if you have successfully added images to your feeds.
If you use Google Chrome, there’s an extension that lets you view the feeds visually.
- Install this Chrome extension – RSS Subscription Extension (by Google)
- Once installed, this extension auto-detects RSS feeds of any website, allowing you to click on it to preview the feed content.
You can see that the extension is pretty popular and is used by 976,372 users at the time of writing this post. This also shows RSS is not dead yet!
If you use Mozilla browser, you can navigate to your feed URL and see your changes in the browser itself.
I hope this post helped you in adding featured images to your WordPress Feeds. I would love to hear which plugin you used and what worked for you in the comments below. Also, let me know what you think of RSS feeds in general.
