In my quest for finding a good photolog (and creating/writing my own) I have come across some very interesting sites, tutorials and such. Here is a list of sites out there. This list is not biased in any way and could easily be extended and appended. Please feel free to email me or leave a comment for others.
– MT Photolog Conversion tutorial: Great resource. Looks like there are a bunch of ways to convert a Movable Type installation to a photolog!
– A list of photolog software online (mostly paid, from photologs.org)
These are only a few that I have found. I am, of course, looking for more. I want to incorporate the best of these into WordPress (or die trying ;-)) Please let me know if you know if any others.
