(I just realized I might have posted this in the wrong place…sorry! Still…trying to…get the whole…change…thing…)
EDIT: I wanted to note it DOES show up when rendered, but, not in the viewport. It just has…flashing colors when I rotate it. Also, I’m on Windows 7 64 bit.
Sample as lamp isn’t going to affect this-it’s just about efficient sampling and noise reduction. Could you share the file? It’s hard to tell from this. Try to switch the background to the sky environment and see if it works. Then try to switch it back to your map.
Numpad 5, not just 5 above your keyboard. Numpad 5 takes you to ortho or perspective, and you need to be in perspective. You can check it in your header menu under view as well. I tried with an image on my machines, and all three work as expected in perspective view.
I hate to repeat what everybody else has said already, but that looks exactly like ortographic view.
Have you tried you to change Ortho/Perspective in the menus as well? Just to eliminate the risk of it being a keyboard issue. You find it under the “View”-menu in the 3D View.
