Verify the resolution size of a single image.

During the last stage, when sorting through images, if there is only 1 image left to be merged it will result in an overly large image of that single image that will take up the entire page to print. This should be investigated more to see if the resolution and/or PPI/DPI needs to be adjusted for this edge case.

This may also affect 2 and 3 remainder cards as well (1, 2, and 3).
