This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.


You can improve the default WordPress RSS feed to include:

  • This plugin will add post thumbnail to RSS feed as “media:content” and “enclosure” tags.
  • Image is also added to HTML part of “description” and “content:encoded” tags.
  • You can also add server signature to end of feed content in form “Source: XYZ”.
  • Inject advertisement (image with link) after nth paragraph of each post.

Post thumbnail

Add post thumnail to each post’s excerpt and full text (if enabled in WordPress configuration).
Image will be added just before text of each post in RSS feed.
Post thumbnail is also added as media:content and enclosure tag to RSS feed.

Full-text RSS Feed when accessed via special URL

You can access RSS Feed with full content posts even when WordPress is set to RSS “Excerpt only” mode. Just setup a “secret key” and enable the override…
You can then request feed url with special query param ?fsk= to override “excerpt only” mode to “fulltext” mode. This is great for services like Google Currents.

Server signature

You can add server signature just after the full text content of post to each RSS post.


Very simple implementation of advertisement to each RSS feed post item. Ad is a simple clickable image (stretched to 90% of width – maximum of 700px).
There is no click monitoring, so you should use something like to track clicks.

In the code there are various settings that would allow you to toggle adding the RSS image to content and excerpt and so on, but they don’t appear. The settings page is blank of any actual settings… You can’t even customize the image size in the feed, and a support thread asking how to do so is still unanswered. I think this plugin is abandoned.

The plugin works as advertised and also helps MailChimp to deliver posts images from my RSS feed. Thank you, Ladislav!
