I've noticed that images uploaded as avatars do not crop to a standard size. I've tried cropping my own photos there but there doesn't seem to be a way to do that. Ideally, I'd like to see photos cropped automatically to a standard size.
It would also be nice to choose from uploaded photos. If I have a photo that I used before as avatar and then changed it, it seems I have to upload it again. Right now to change the photo, only options are to upload or use webcam. An option to choose from already uploaded photos would be great!
