Ah ok... i just once got a .psd file from J.Edward and could work with it in gimp without further problems (well, i havent testet evrerything possible in gimp with it). Since it's possible to export a gimp project into a .psd file, i hoped it might work. Nonetheless, i wrote in the updated first post, that there is no guarantee the .psd files i uploaded will work properly in PS. Since Diamond asked, i just wanted to give the possibility for anyone interested in it, to experiment with it.
Cheers,
AL
