Those 4 images are all thumbnail templates.
There are tons of ways to do thumbnails, and they are incredibly simple.
You can do it digitally on your tablet/computer.
You can pull out a piece of paper and draw a bunch of little boxes and rough out the general shape of the area of the body that you’re working on.
I like to use simple premade templates like the one below. I’ll basically starts with a #2 pencil, I’ll print one of these templates out...
Or I’ll pull it into Photoshop and add a layer on top of the template.
