Best Themes With Auto Thumbnail?

What are the best themes for autoblogs that automatically add thumbnail from rss feed/ post?

If there are any. I've tried 4 or 5 premium magazine themes and they don't seem to add my thumbnail automatically. Am I doing something wrong?

well I have this problem too with the premium themes

but you need to use custom

and image image or thumbnail thumbnail

and check the feeds your pulling have images etc

the creator says this works - but not so far for me


I just use the post - the complete post and avoid thumbnails at this stage
