How do I set a comic wallpaper on my iPhone?

To set a comic wallpaper on your iPhone, first download the desired image. Then, open the Photos app, select the image, tap the share icon (the square with an arrow pointing up), and choose 'Use as Wallpaper'. You can then adjust its position and zoom level before tapping 'Set Wallpaper' and choosing whether to set it for your Lock Screen, Home Screen, or both.
