You mention copyright issues, and I assume that means that you uploaded images that were copyrighted and now want to delete them. If you can tell us what profile(s) the images were added to, and perhaps the names of the images, someone else can probably delete them. If they're on open profiles, any of us should be able to do that. If they're on private profiles, then you may need to write to info@wikitree.com and explain the problem. If you don't know where the images were posted, then I'm not sure that having your old user name and password would solve the problem, or that anyone else will be able to help you.
