which version are you using?
I've got issues with thumbnails on category pages: they are distorted. Please see the example here: Gaggia | Raw Espresso
I've tried to upload another picture for post, it didn't work. I also uploaded new thumbnail and adjusted the change in custom field. It did work but thumbnails in the right hand sidebar changed too: for the worse, they look badly distorted. Is there any way I can have nice thumbnails in both category page and side bar? Would disabling automatic image resize script help to solve the issue? If yes, how do I disable it?
