I just updated the software used for the photo gallery. It only took me 2 reads of the original install instructions and then I slapped myself for chmod'ing some files incorrectly. If the instructions say 777 and I give them 755, I shouldn't be suprised that errors show up when saving the configuration, should I?
Anyway, it's all installed now and the albums have been upgraded. This version is supposed to be (mainly) a bugfix of the previous one and not too much new functions have been added, so I think it's pretty safe. I'll keep an eye on the developers forums though to see if anything shows up that might compromise the server or security.
