Earlier quoted context omitted.
Wife still uses Photoshop CS 2 on Windows, and I've basically told her that when her computer dies, she's getting Linux and open source software, or she's gonna have to figure out Windows 11 by herself and pay the subscription for Adobe. "Fine with Linux" she says, since it's installed on other computers in the house, "... but what can I use instead of Photoshop?". "Use Gimp, of course!" I say, and install it on her…
You'd better test if her Photoshop works fine with Wine. If it does, nobody get frustrated, there is no need for her to relearn everything from scratch if she is satisfied with that tool and her workflow established over more than 10 years, and you don't have to pay for a new tool.
It does! Some very minor UI issues but very usable. Actually, I've got an old trial version of Photoshop CS6 (I think? Whichever was the last version they released as locally installable) and it also seems to work on Wine. But you can't buy that any more :(
