Hall Bernd,

Thanks for your reply. Yes, a batch would always be possible but I would 
like to avoid it if no necesarry.

The strange thing is I add one of those tiffs to an textWithImage 
content element, the image is rendered perfectly. So that means that GM 
does not have problems to convert these images but it should be GIFBUILDER?

Any more ideas?

Thanks in advance!

Bert
