Sure, http://i51.tinypic.com/10ejza8.jpg. As you can see, one side is aligned correctly while the other is not (it's a problem with my frames which I'm trying to get adjusted). My goal is to move it so that the crooked portion is fixed, if it's possible.

I wear glasses and in most pictures I'm in, my glasses seem to be crooked and not aligned with my eyes correctly. I wanna know if it's possible to straighten them. I've tried selecting them within a new layer and using the Rotate/Zoom tool, but that doesn't help. Any suggestions on what to do? Also, if Paint.net isn't capable of doing this, is there another free image editing program that is?
