Is there an app that lets me pin a picture in front of whatever I'm doing on my tablet?

I'm looking to use it as a reference image for artwork on my Note Pro 12.2. It would be great to be able to just have a moveable, resizeable picture pinned in front of whatever I'm doing that I could move around depending on where I needed to be drawing. Let me know if you can think of anything! Thanks!

There's probably an app for that..
Do you have split screen on that device?
