If she shoots a gun, her power would leave behind a sort of afterimage that continuously shoots at the same spot until something interferes. If she shoots her own image, it would send it flying off shooting all over the place until it hit a wall/floor. If someone else throws a rock at it (hell even a leaf), it would shatter the image and negate it. Anything more complicated than that I've set aside for future progression.

Anyways I'll plug in the extra stuff. I think it's ready for review.
