The problem is solved. (I installed an other pdf viewer and with this it works.) Probably Silke uses an too old version of acrobat reader which does missinterpret the permissions (e.g. the images have to be rearranged because we do not use letter paper format in Germany, and it might be, that this is forbidden) - whereas the new viewer ignores these permissions. But this are wild guesses...
