Best cropping for thumbs
 

Are there any generally acceptable best practices on cropping methods to generate more clicks? I was adhoc cropping images to generate better looking thumbs from the TGPX auto-thumb scanner and was doing according to my own sense of what looked better.

Another site I was looking at had guidelines on cropping thumbs for submission to their TGP gallery and they said it was best to concentrate on cropping a closeup of the face vs the whole body.

Thanks!

very good question

crop till you drop
