I have seen other people change their picture after it's been uploaded, like having re-cropped or something, and I can't work how to do it. I have an Ace membership. Can someone please talk me though it? Thanks!
If it's not deleted and uploaded again, they are using picnik. Look for Edit with Picnik when you have your picture open. It's listed under Ace Tools. Keep in mind this application will be unavailable soon.
