Where did my lock screen picture go?

I have used the effects to create a picture I really like for my lock screen. I update my phone today and that picture is now gone. Why? I can't seem to get that exact picture again. Why did updating my phone ruin my lock screen?

Hey there! I have just a couple of questions!

Were you using a theme or an app to get that specific background? If so, what app?
