Lock screen image

[joe bakewell]

I was watching a youtube video on my s5 (lollipop) and now my lock screen wallpaper is set to the title screen of that video. I did not change it and have since set a new lock screen wallpaper but the image still remains. There are no downloaded images in my download history nor is the image anywhere on my device. I have closed and reset youtube as well so the video isn't running in the background or anything. Any suggestions?

Oh scrap that, I just restarted my device and it worked itself out -_-
