RSS Custom Fields Images

RSS Custom Fields Images

Details
View on WordPress

This plugin will extract the large version of an image attached
to a post and put it in front of the content in the RSS feed.
This might be useful if you have an image (and only a single one)
attached to a custom field and it won’t display in the feed otherwise.
