you can also use something called Windows Paint, which is as very basic photo editing software.
from the Start menu, go to Program Files>Accessories.
there is something in there called PAINT.
actually, all you have to do is Right Click the properties of the picture, and click EDIT.
it should open up windows Paint. click on the Image local, then stretch/skewer[ctrl-w]. shrink the picture by 50%, or however much you want then save it. this is the easiest to shirnk pics.
also, MOST digital cameras come with some sort of basic picture editor.
