I took a brief look at the site in question with Mozilla and Internet Explorer, both of which were able to render all the images, so I'm guessing there is a problem with the standards used to write the html code, and Netscape 7 can be very picky about some things. I don't see any errors jumping out at me when looking at the code, but you can try a validator to check the html code and see if its compatible with Netscape 7, go here: http://validator.w3.org/
