Right. I can't remove them.
Now, it is problematic to me, as some of these images are declared being 
from me in other places (and it is important that they are from me *over 
there*), while now, they also exist in another website, apparently owned 
by another person, and not clearly gfdl any more.
So, my offering them under gfdl to Wikipedia (that is, normally 
preserving my authorship) is likely to hurt me indirectly in my real 
life as some one could claim being the author and having a copyright on it.
If I can't remove them, I suppose however that I can replace some of 
them with identical images with a gfdl license embedding in ? That will 
not make it for the ones now lost, but at least, future pictures and 
future uses will be saved ? Of course, the embedded licence can be 
removed, but it makes things harder. Can I do that ?
If Wikipedia itself does not try to secure its participants rights, how 
far can we go to preserve the rights we should have in our participation 
under gfdl Michael ?
