Project Seven contact?

Some of you old timers may remember me from my heyday with Dreamweaver in the late 90s and early naughts. And I even see some names here that I remember. Well, anyhow, I am in the process of re-hosting a very small site built in the mid 90s using one of Project Seven's wonderful extensions. At this point I can't remember what it was called but it implemented a linear array of thumbnail images that would enlarge when clicked. Now, to test my ability to get this site going again, I uploaded it to a subdirectory on another site, browsed to it, and it worked perfectly. Now I have uploaded it to a "holding" location on the new host site, and the images are there but they don't expand when clicked, instead they just shudder annoyingly. So, it works in one place and doesn't in another. I'm sure that Gerry Jacobsen could diagnose the problem immediately. Does anyone know how to contact him?
