Hi folk!
If someone has an errors with this mod, try install it to running webserver, not localserver!
When I tested this mod, I had errors too (I use for testing local vertrigo webserver) and had had almost every errors mentioned in here.
But after I installed mod to on-line 4images project, it works perfectly, without any error.
So, I am sure many of us has these errors only because of using local webserver (it has to be fully featured maybe).
