that is gd2; i recommend ImageMagick if you have it installed.
the error just means you havn't set an image processor; go to the gallery page in your cp and submit it (with GD selected)
OK, color me confused, Gizzy.
According to my CP, in the Gallery Settings, it says this:
What Graphics Library do you want to use?
and the only item available in the pulldown menu is "Use GD2"
I don't know anything about ImageMagick and how to go about installing it.
