How to improve your DTube thumbnail images | Add text, PNG shots, frames etc

I definitely think improving your thumbnail images is a good way to increase the views on your videos. That has been my experience at least, so I thought I'd share with you how I edit these "snaps" (as they are called on DTube).

I use the website called canva.com.
That is how I add text, PNG images and more to my thumbnails.
I have used Photoshop and still do from time to time, but I have found Canva works a lot better and is also quicker to use.
Let me know what you think in the comments! What do you use to edit your thumbnails?
