Thanks for the effort to both of you.

I can?t open your files with irfanview, xnview or any other kind of "advanced" pictureviewer, yes the basic windows-picture software works but this program is lacking
in my opinion.
Sadly I can?t tell you exactly what the problem is with your data (the unedited pictures from the g.e website work fine) - is there a possibilty that you look into this matter?
