Gallery2 is a web based PHP gallery system with a remote API for doing many things. I have been using it for a while, but have decided to change and so I wanted to export my images, which is harder than it sounds. To actually get this done I ended up writing a basic wrapper for the Gallery2 remote API and implementing a small console application to do the export.
If you are interested in the wrapper or the tool itself, I have setup a CodePlex project for it where you can download those: http://gallery2.codeplex.com/
The reason it is there, is because I have decided to open source it because it is useful to people besides me and I have gotten what I need from it, so I doubt I’ll spend much time getting it feature complete. This way someone else can get the tool (if that is all they need) or get the source and add to it.
