Matt emailed me asking how to do the little photoset thingy I've got in the sidebar. I initially sent him back the code we're using, but it's got a lot of unnecessary stuff in it that serves to merge Catherine and my photosets, sort them, and distinguish them. I took another pass at it this morning and stripped all the unnecessary junk out. I figured that others might find it useful, too, so here you go.

It's not rocket science — this is very simple PHP. It's just that it makes use of a couple of useful third party libraries. You'll have to install those, which can admittedly be a pain in the ass, particularly in the case of PEAR. But it's definitely doable.

Of course, after doing all of this I remembered that Matt's on blogspot, and consequently is probably unable to install the necessary PEAR libraries (or even use this script). But some borderless IFRAME action should be able to get around that (hacky though it may be). For folks with webhosts of their own, there shouldn't be any problem.
