Can you please check if the image you're trying to upload is in .jpg, .jpeg, .gif, .png format and at least 250px by 250px? Also, make sure that it's a clear photo of yourself, not a long shot and your face is clearly visible. If it meets those requirements and you still can't upload it then please try clearing your cache and cookies and using a different browser to check if the problem persists.
My photo is only 624 KB and there is no save button. The only active things after I get image cropped is the "upload a new picture" and "edit" which is an "X" that closes the window. Seems like a simple add that should take 1 minute and instead messing around with it for 20.
