I know this may sound like heresy from an incurable Flickr fan, but what’s the best local-install gallery software out there these days? (Occasionally I want to slap together a big heap of images without shoving them in front of everybody, so a local gallery would be nice. I’ve got some ancient PHP scripts that I used to use on dsandler.org, but something a little more modern—and lower-maintenance—would be ideal.)
