how do you change the wallpaper without changing the lock screen photo?

Use the Settings app to change your Wallpaper.

Settings > Wallpaper > Choose New Wallpaper

Once you select a new wallpaper you will have the option to use that Wallpaper on the Lock Scree or Home Screen or Both.

If you want to keep your present Lock Screen Wallpaper just select Home screen when the choices appear.

Hi, Thanks for your reply.

When I choose the wallpaper two options appear at the bottom of the screen:

Cancel and Set.

I do not see any option to choose between Lock Screen and Wallpaper and I am afraid if I select "Set," it will delete the personal photo I have on my lock screen and I will not be able to reset that photo there.

Am I incorrect in thinking that if I select "Set" both the Lock Screen and Wallpaper will set to the iPhone image?

By selecting set it is asking you if the image you have is set correctly. Then after that you get an option to set as lock screen, wallpaper or both.
