Cool, well if you go to toolpic.com and load your template, you add say a mask like adding images here but they call them layers over there. You add your layer and then click on edit and you get options to turn it around or even stretch it out. You can even erase parts of it or add other layers to it.
Anyway, if you decide to give it a shot and have any questions just ask I'm usually not away from a computer for too long when I'm working.
