Snippet Library
RSS Feeds snippets for WordPress
Snippets for WordPress RSS feeds: add featured images and custom post types, delay publishing to feeds, credit your site on scraped content or turn feeds off. For publishers and podcasters whose readers follow along by feed or email.
Featured Images as media:content in RSS
Adds each post's featured image to the RSS feed as a media:content element, the format email newsletter tools and feed readers use to show a thumbnail.
Feed-Only and Hide-in-Feed Shortcodes
Adds [feed_only] and [hide_in_feed] shortcodes, so you can show a special message to RSS subscribers or keep interactive parts of a post out of feeds.
Fix Relative Links and Images in Feeds
Turns relative links and image paths such as "/about/" in feed content into full URLs, so they work in feed readers and RSS emails.
Remove Images From Feed Content
Strips images and image captions from the content sent in your feeds, keeping feeds light for readers and services that only want the text.
