Ok, I do not have an idea how I can write a script for changing CMF 
documents within a zexp-file. The documents are within the ZODB and I do 
not have indeep practice for this. Maybe it's easy, but I do not know it.

Well, what do I have to do, that I will get upper case into lower case. 
With changing cmf:registerDirectory it has no effect as I've described 
above.
In ZMI checking the properties of the Filesystem Directory View all is 
written in lower case but the UserWarning means it is Upper case. Even 
though the path in the Warning is strange because it is 
"...skins/custom_image/..." and not "...skins/mytheme_image/..."

Probably I will not see the easy solution.
