I just upgraded our gallery software to Gallery 2, from the 1.5.1 version. This looks pretty cool. I really like the external modules that can be enabled/disabled individually.
It did a great job at importing the photos and albums from the previous version of gallery. One things that I found out is that you shouldn't cancell the import while it is in progress. When I did that, and tried to reimport the data, it failed. I had to drop all of the tables, and delete the data directory.
I also noticed that it creates 43 tables in the mysql database that it requires. I haven't gone through each of the tables to see what data is stored in each.
