Yes, that was me. It's not Photoshop, but has many of the same features and seems easy to use. And best of all it's FREE.
I made this with it on my first (and so far, only) attempt:
The free software is called paint.net, recommended by coollew to me. you can see by his memes what can be done. It's no secret he's one of my very favorites.
He also recommended a great installer that does everything, including saying NO to all bloatware (toolbars, etc...). This one is called Ninite and I like it a lot. You just check the one(s) you want (paint.net and/or dozens of other useful FREE utilities)) and click install. Done.
Here's the link. https://ninite.com/
I'm sure you'll enjoy the editor - it's got tons of great features. Good luck!
And I hope you'll follow up with links to your new masterpieces. :-)
