Featured images not displaying in Autoblog posts


I am trying to display the featured images from a feed but they are not showing up. The default image is showing up fine, but I can't figure out how to get the featured image to display.

In the feed editor, I've tried each way to display the featured image...
- use media:thumbnail tag
- use enclosure tag
- use first image in content
- use last image in content

None of these are working.

In the Addon section I have activated "Featured Image Import" and "Image Import". But still it's not working.

Any ideas of what I can do? I've also tried this on other feeds and it's not working for any of them.

Thanks in advance!
