>We are having a problem with an outside firm that is creating some art work for us. They are using MACs to create this Jpeg image. But everytime they email the file to us, we can't bring the file up. And, if they send it to us on a Zip drive, our PC can't even view the contents of the zip disk.

The format of the zip drive seems to be the problem if you cant view its content.

If the files was not too big, tell them to send it by e-mail...
