Will follow the lead of everyone by complimenting you on a great piece of software!
However, when I upgraded to 0.9, i don't think the path detection stuff has worked properly on my server. My index.php now links to the galleries at http://tignes/
(for the Tignes photo album), whereas with 0.8 the link went to http://www.skinnyjimmy.com/skinnyphoto/tignes/
I am not that hot with .htaccess, but did change the rewrite base to /skinnyphoto (this is the directory which holds all the zenphoto files).
Anyone have a clue, before I drop back to 0.8 in the morning?
