I spent a while trying to figure this out. Well…. I finally did it! I added thumbnails to the TMS RSS feed. So if you want to add post thumbnail images to your TopMediaScript media site then download the RSS feed generator file.
Download the feed generator.
1. Back up your original file called generate_rss.php.
2. Extract the new file called generate_rss.php
3. Then upload to your server.
4. Login in the admin area. Then click Update RSS Feed.
Last: View your RSS feed http://youwebsite.com/allmediafeed.xml
Thats it you should now have thumbnails in your RSS feed. Enjoy!
