do what phil said its is the same thing i do. When you open paint go to Image then strectch/skew and then change the the horizontal and vertical settings only. Start with 80 for both then close the stretch/skew window and go to image then attributes and it will tell you the size. your problem is not the horizontal X vertical size (800X600) it is the size in kb which is how much space it takes up. So by making the image a little smaller it will take up less space.
