Okay Chris!  I'll try this out.  I was just throwing reasonably sized images in as needed.  I'll try re-sizing to see if it works and report back.

I managed to test this on a slightly newer MBP with a Core 2 Duo, x64 running the same OS 10.6.  It worked fine like the PC I tested on.  

Does anyone else have a MBP with a 32-bit CPU running a similar OS and Mathematica version that would be willing to help try and reproduce the bug?
