I would suggest using Imagemagick if it exists on the server and then be mindful of your server limitations regarding upload sizes in PHP and place in edit usergroups a restriction on the size a photo a user can upload that way they get the proper messages and do not lead to them crapping out your server's PHP where your going to get no message or nothing
