Well... I guess the first thing I would do is creat a static navigation bar... one that has "Home" and the names of each of your major projects listed. You cannot navigate at all on the site without using the 'back' button.
Also, it might work better if you create your photo page so you can see the thumbnails of the prints say on the left, then clicking on a print will cause it to appear larger on the right. That way, the user does not have to keep going back & forth either through the images, or using the back button to get back to the thumbnails.
Hope this helps! Oh!!! One more thing!! From a usability standpoint, if you could change your font to a sans serif font (such as Arial) it will be much easier to read. (A little bit of online usability trivia).
