Why is it that whenever the method of images is used to solve for the induced charge on a grounded conductor in the presence of a point charge, the total charge is just the same as the image charge?

Gauss's law says that [tex]\oint{\bf E\cdot dA}[/tex] is given by the total charge inside.
This is either the actual surface charge or the image charge, since they give the same E.
