Could be an issue with the color map - investigate GD::Image->trueColor(1) or GD::Image->new(h,w,1) note also, GD::colorAllocate returns -1 if no color is allocated - check your return values - always (regardless whether your working in Perl/C/Java/BrainF*ck/whatever)

You could try allocating more and more colors until colorAllocate starts returning -1 to check the size of your color map - though I think it also depends on the color maps your apps run, leading some apps to declare private color maps
