You can use Gimp, which is free, powerful and really stands for a solid Photoshop alternative. If you don't need CMYK related functions, I recommend you to check photopea.com . It's simpler than Gimp, but it's very useful. Its interface and shortcuts are very similar to Photoshop.

I always found Gimp very unintuitive, even though I've known it for many many years now.
So I was very happy when a new alternative showed up in the repositories which is better in this regard in my opinion and that's Krita.
(It's also available on Windows, btw.)
It's still not Photoshop, but oh well, many functions feel really good to use in Krita.

Surely you meant Glimpse, rather than that patently offensive other software that shall not be named.
