Welcome to Android Central! Not all phones have this option. You could see if there is a custom ROM designed for the phone that has the feature, like CyanogenMod.

If you are using a custom launcher such as Nova Launcer it won't work, you will have to use the default BLU launcher in order to change the lock screen picture.
