Image problem after swapping servers

I swapped servers on my shopping cart but I am now having some issues with it. I cannot edit any of the product or category images. Some of the product and category images show, and some do not, but when I try to change them they either will not show, or will not update on the customer side.

Any help/thoughts/pointers would be great. I did a couple practice server swaps on my old server before moving and all of those went flawlessly, so I am a bit confused now. Thanks.
