Picture Of A Dongle Switch What's A Photo Or Picture Editing Program Kind Of Like Photoshop But Free?

What's a photo or picture editing program kind of like photoshop but free? - picture of a dongle switch

I tried Paint.Net and Gimp, but very confusing.
Do I use sometimes Photobucket Photo editing thing.
Is there a program that has something brilliant? Embellish your skin and makes it shine brighter and brighter?
