These days, and in particular yesterday, I tried to change the blog theme to something a little more personal… I also installed Gallery2 and so I tried to see if it was possible to integrate them. The main plugin I found is WPG2. The first isssue was that it needs Gallery2 version 2.1 or higher, and Ubuntu has an old version. So uninstall apt-get remove gallery2 and install by hand the newest one. Then you need to apply to Gallery2 a theme which makes it usable inside a wordpress blog, and so you need to install this theme and configure it using the instructions at the wiki. Then WordPress needs a theme which plays nice with Gallery2 and altough it is probably not too hard to do it by hand, some of the most famous themes have already been converted at http://dev.cal-family.org/.
