I want to have 1 picture for my home screen, and a different picture for my lock screen. Why have you gone and made this so difficult to accomplish?

3. Tap one of the wallpaper options to select it as your Lock Screen. For some wallpaper choices, you can swipe left or right to try different color filters, patterns, and fonts that complement each other.
