Sorry, your other mail was marked by my mail server as Spam. I have copy-pasted what you send and tested it. It works fine with some "easy" files, but I obtain a blank image with my "preffered" one. Those are my tags:

Do you detect something not compatible with TIFF specifications?

Thanks once more.
