Upload a profile pic, and crop. If it does not look right you should be able to re-crop w/o re-uploading.

The photo is not physically cropped, as seen when clicking, so this should be possible. Thanks

Just open the upload screen, click save without uploading anything g and it should let you do it again. Not really intuitive. I found it out by accident.

Yes it does. They need to add a

"Resize current image"

button on the very top, if it detects an image, that does the same thing that Save button does... for clarity. That would be great!
