There are many other ones about so you can take your pic.
Paul, thanks for the link to Stu’s site. I’ve been keeping half an eye open for a dirt-simple CSS-driven thumbnail gallery display; a client made some noise about wanting something like that a couple of weeks ago. If she decides she wants it, this one’s a good choice. Since she only wants a half-dozen or so photos rendered, I didn’t want a big clunky JS solution. Tide, since you’re looking to render ~50 images, Stu’s solution might not be so hot for your needs.
I don’t usually think of Stu’s work as “simple” but he sometimes drops some really simple stuff in with his complicated (I’d say often overly complicated if I could code half as well as he can) demos. Good catch.
