Installed! Many thanks.
Btw.: Is the sigpic-entry-length restricted somehow? I tried to add a signature-address from photobucket and it?s truncated after saving it. So no chance to use it.

Ok, found the solution in the v1.3-thread. I had to uninstall the product and edit the line "`image` VARCHAR( 80 ) NOT NULL" in the product-xml, choosing 150 instead of 80 for example, and then reinstall the hack. Now it works.
