Try this link
to wikipedia's explanation about .art files.
It seems to be an archaic practice that even IE got tired of dealing with, so they just stopped supporting the conversion. As well, there is a link
to an FAQ about this problem. I tried to look up some freeware plugins for photoshop that handle .art files, but they all cost at least a little
money. I will admit though, I didnt look very thoroughly. Just do a search for (-software package-) plugin AOL.art and you should get plenty of
links to go through.
