The mechanics of Image are actually quite simple. The user must first select some kind of object for a spell. Once they've found one, a sword for example, they can then scan the sword and make a floating copy of that sword. The user can then alter the size of the sword, and by moving the original sword, the image will move in the same direction. However, a user can only make an image of one object at a time, and the bigger the image is, the more magic it uses.
