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 A GPL-type license is perpetual and cannot be withdrawn.

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 Since the license cannot be withdrawn, the images 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 The only images that should be withdrawn are those under 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.

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.
