I use "paint"-just right click on the picture, another window opens and one of the selections will say "open with". move the cursor over that, another window opens and one of the options is "paint" on my vista. I click on "paint" and the whole picture shows, way bigger than the screen. click on "image" at the top and then "resize" and you can type in what percentage of the original size you want. I usually go about 35-40% to start, that's still usually a little bigger that full screen size.Then you can also use "crop" to cut out stuff you don't want in the picture, and you can write on it, draw on it, change all sorts of stuff-like I did the speedometer and Rob's beard pictures. When you're done you have to click "save" ,under "file". Click "save as" to keep the original too, because once you click "save" that's what it'll be, and you can't get the original back. "Save" is fine if you're just resizing, but if you're doing other stuff to it, you might want to do "save as" so you can keep the original photo too.
