Lock screen wallpaper samsung galaxy s4

[kokopely]

I downloaded an app from the play store. It is a selection of wallpaper. How do I put it on my lock screen? When I select the picture it says set wallpaper which is does but to my home screen. I have gone under settings-my device-display-wallpaper-lock screen but the app does not show up only gallery and photos and some silly travel wallpaper on the lock screen.
Any help would be appreciated.

Thank You

Are they live wallpapers? Since the 4.3 upgrade, it's no longer possible to put a live wallpaper on the lock screen, unless you put it on both the lock screen and the home screen.
