I have a ton of pngs, jpgs, webps, mostly of fantasy art. I want to be able to mass-tag them with things like "character", "environment", "elf", "demon", etc. and then view them based on tags. Can anyone recommend software like this for linux? Bonus points if it also works on windows. Thanks!
I know KDE's Dolphin has this built in, but I'm so afraid to use it because I imagine it'll take ages, and it wouldn't be recognized by anything else. 😬
Just to add...because xattr it's also "easy" (for some definition of easy ;)) to add/modify tags from the shell making mass-tagging feasible (as requested by OP). Second answer here should give a decent starting point....
