I don't get VI errors but I am not getting any display.

This is the problem that I am having, nothing seems to come into the Image Pixels (U8) on the Front panel. I don't get an image, the image box just stays white and nothing at all comes up for the pixels. What do you think is going on? I was wondering where I could probe the VI so that I could figure out if anything from the image is getting through. Where would I do that? I want to make sure the VI is getting something from the IMAQ board. Also what kind of probe would be the best to use? (I know it depends on what I am probing).

Try changing the input to the For Loop iteration terminal from 4 to 256, as done in the following example program.
