My $0.02--might have absolutely nothing to do with the problems you are having! I had strange problems with my image code which were due to the font I used. My code would run sometimes and sometimes die in the gate. Seems that you need a "unicode" font, and not all true type fonts are such. Hoping you'll get your problems resolved.
