why won't my IPod wallpaper change?

[iMore Question]

I wanted to change my lock screen wallpaper so I chose a picture from my Camera Roll, but the lock screen wallpaper didn't change into the picture I wanted.

Which iPod are you using? Can you send a screenshot of what it looks like when you try to change the lock screen wallpaper?
