Let user choose how a photo is cropped for thumbnail use
Be able to select how a thumbnail of a posted image will be viewed rather than automatically cropping the center of the image.
Something like Facebook's tools for zooming in the circle of the image you want to set as you avatar would be nice as well. I'd really enjoy this!
I don't know how the auto-cropping face detection feedback got an editor's comment but THIS one didn't get anything.
crop tool for photos, will improve control and privacy.
Ability to adjust displayed cropping of profile photo
Option that enables to position image of the profile picture preview.
Once a photo is uploaded make users able to edit it, crop it, resize it etc.. would be awesome!!
