I am looking for nice looking and with good usability photo blogging software to run on my server. So far I have found PixelPost, Cheesecake and EZPX. PixelPost - look quite abandoned project Cheesecake - also quite abadoned EZPX - Not sure about it.
Wordpress has documentation dedicated to photoblogs and galleries. Everything you would want to know setting up Wordpress to that is right there.
