AFAIK, mtPaint is 'builtin' to all Puppys. I wondered why. don570 has long advocated its use and even provided a tutorial, https://oldforum.puppylinux.com/viewtop ... =94018&i=1. Dingo has called it "a little gem". Little, indeed. The fossapup's 64-bit version is a 360 Kilobyte pet.
But I always installed/SFS-Loaded gimp. Gimp is now available as a 161 Mb AppImage. [FYI, Krita @ 184]. Packaged otherwise they may be slightly smaller.
I can't draw my way into a bath. But if someone else provides the pieces I can do a little cutting, erasing, color correction, resizing, and pasting and end up with IMHO a nice 'patch-work quilt' such as fossapups* in the madagasgan jungle:
Gimp has 'upgraded' to qt5, added some 'bells & whistles' by --I think only-- providing two slightly different versions of the same modules; and somewhere along the way lost sight of the main purpose of any application: usability. Erasing has become more tedious. Saving an 'erased' image doesn't always work. Pasting doesn't always work as expected. Eventually, to produce the above wallpaper, I gave up using Fossapup (where older versions of gimp wouldn't function) and booted into Bionicpup64 where they would.
And during respites from that torturous journey, I started looking for an alternative graphic editor. There are others; you'll find them on the Forum's Additional Software Graphics. And I also discovered mtPaint. And why I've avoided it. Like Puppy, itself, it has it's own way of doing things. For example, it doesn't use tabs, or even separate windows running under the same Application. But, like rox, you can run multiple instances of the same application.
[I don't know if that's been mentioned anywhere. I discovered it almost by chance. While perusing documentation I came across the fact that mtPaint can create animated gifs. To do that you have to be able to combine several graphics within/under a 'master'].
There may be other, simpler, ways. I have yet a lot to learn and will have to follow the advice given as the title of this post. But hopefully, perhaps mtPaints' documentation is now a little easier to access. viewtopic.php?p=30750#p30750

* I don't know what fossa young are actually called. While 'cat-like' in appearance, it's closely related to the mongoose family Herpestidae. fossagosling? Well, a baby mongoose is called a Pup.
