Easy. Start at Gallery, then tap on
All Downloads. After you see the photo you want to view full screen, tap ONCE to automatically view the photo at 75%, then DOUBLETAP to go full screen. You can also use the pinch and zoom style with two fingers, after selecting your photo, to resize the view. Pinch inward to zoom further out/make pic smaller, or pinch outward, to zoom in to FULL screen and then some. Either way, play with the second option and you'll see what I mean in no time.
