I'm having trouble with my online photo gallery in Photographyreview. Perhaps someone here can help.

This is my problem:

I save an image as a jpg and it looks nice and sharp when I preview it in internet explorer.

I then upload it to this site for my gallery and it looks fuzzy. This has something to do with the size it becomes when displayed in the gallery. i.e. when it is forced to fit into the constraints preordained by this site. I'm pretty sure there is a way around this maybe something to do with how the photo should be originally saved in photoshop. Unfortunately, I just can't figure it out.

I am using photoshop 7's image ready to save my photos. Any help would be greatly appreciated.
