By the way, is it okay that I relicense all the images I offered wikipedia as copyright by Anthere with permission, with a link to my user page, instead of under gfdl ?
You can choose to allow that use _as well as_ the GFDL you've already agreed to. But, once given, I'm not sure you can withdraw the GFDL permission without cause. (IANAL!)
Actually, I'm quite sure you can't withdraw it "without cause," and I doubt you could find a reason to withdraw the license "with cause." The text of the GFDL specifically states that the license is "unlimited in duration". A GPL-type license is perpetual and cannot be withdrawn.
Keep in mind that if you were to withdraw the GFDL license, the images would be removed from Wikipedia.
No, they shouldn't be. Since the license cannot be withdrawn, the images stay. By uploading them to Wikipedia, you agree to the terms of the license. The only images that should be withdrawn are those under copyright, if the user did not have authority to grant a GFDL.
I have doubts. Many images are indicated copyrighted, but that the author gave permission for use. And they are in Wikipedia.
The images may still be copyrighted. The GFDL and copyright are not mutually exclusive. However, the author's permission must be GFDL, or something less restrictive than the GFDL.
