Gahhh!!! Once again, everytime I go to the front view, the actual reference image disappears and I'm just left with a white plane. Looks like I didn't fix it last night when I tried, so if anyone has any more ideas on why this could be happening, please let me know.

Not only just in the top view now, but anytime I re-open my file the image is gone with just the white plane left in all the views. Nothing happens when I press 6, just the white plane.

I can't catch a break now, so on top of that problem, all my manipulating tools (Move, rotate, scale) have shrunk to an unusable size, so again, if anyone knows the solution...
