How to turn off photo shuffle display when phone is in lock mode.

I had no idea how I turned this extremely annoying feature on in the first place, and all the replies I've found so far for how to turn OFF photo shuffle on locked screen refers you to the wallpaper settings. Actually, nothing in Wallpaper settings worked to turn it off. However, when I went to settings I saw "StandBy" above the wallpaper settings in iPhone and THAT is what you have to click on to turn off that annoying feature. "StandBy will turn on when iPhone is placed on its side while charging to show information like widgets, photo frames, or clocks." Now, I don't know if there's a way to turn off photo shuffle and still have the other items like widgets or clocks appear, but at least I don't have to deal with annoying photo shuffle, ESPECIALLY AT WORK where some of my photos might not be appropriate to display in public. Come on Apple, do better. There should be a MUCH SIMPLER WAY TO TURN THAT S**T OFF.
