Background Image in 2.5

Right before someone chews me out I DID do a search and came up empty. So anyway I went to view > properties > checked the add background image > pressed add image and nothing happened. No window popped up, no image appeared, no options were presented, nada. I’m trying to add some reference images. Am I doing something wrong?

Remember to go into orthographic view (numpad 5) to show the background image.
