Thanks everyone for your input and feedback. I was pretty sure it was
"operator error" from the start but since both Qt 4.7.1 and VS2010 are both
new I wasn't sure if what the issue might be.

 And to those that suggested options for my large images, thank you so much.
I will take a look at each suggestion and make appropriate code changes.

Thanks
