If you have a web site were you display digital photos, consider using a javascript lightbox to display the photos. When using a lightbox on a link, clicking the link results in graying out the screen and popping up a new window over it that displays the contents of the link. The user then interacts with this new window (the grayed-out main window is not accessible) until it is closed, then control returns to the main window. This is really nice for displaying pictures, presenting login widows, or anything else that is a "detour" from the current page and then brings them back. Using the lightbox code from the link below, all you have to do is make a minor change to the link on your page, include some javascript files in the header, and the lightbox is fully enabled... no programming required.
