Credit goes to @dipstick for the remove.bg link and giving me a tip on how to work around the size limitation for masking object in Paint.NET.
In this video, I used this website, unsplash.com, which is a nice stock photo site, and have already picked a stock photo for this purpose. I utilize this website for nearly all of my photomanipulations and using remove.bg is an awesome site to use.
