With this plugin, an MRSS namespace is added to the site’s RSS feed to include each post’s thumbnail.
WP Feed Post Thumbnail is very lightweight and only adds two small options under Settings -> Reading.

Feed Post Thumbnail

Tried refreshing permalinks, saving settings on the General settings page you've added the two checkboxes to, nothing makes a difference. No post thumbnail in the feeds...

Update! And then it started working!

I'm guessing this may have had something to do with either my hosting's caching or possibly even just my own browser cache. Works like a dream, thank you!

Not adding anything...

Adds MRSS namespace to the feed and uses post-thumbnail as media element in the feed. Settings available under Settings -> Reading.
