If you remove the second image, does everything start working again? If so, what happens if you use a different image?
Another thing to check would be to make sure that you are adding the images in order. If you add image 1 then place the second image in the place for image 3 without anything in the space for image 2, it can cause problems.
Thanks! However, neither of those things are the issue. When I removed the second image, the blank screen continued. And they are in the 1 and 2 spaces appropriately. I have even tried deleting the plug-in and reinstalling it.
Any other ideas as to what might be going on?
