Is that they are designed to share, and the bandwidth can't take it. You can use AW for images under a certain size. Sometimes PNGs work for me, sometimes they don't. JPGs never work. They always turn out fuzzy.

AW it seems only GIFs under the allowed restriction is all you can load, but it is wierd, because I nave loaded up big PNGs before.

Anyway, Marta, it seems that you can only upload GIFs at this time.
