Maybe something like hydrus. Its an offline hosted image-board on your PC. Its allowed you to tag your images for easy find. You still have to find the image in the app and right click it and open in mint image view then right it there again and choice "Show containing folder" option. Keep in mind that the flat-hub version is unoffical but you can also run the official windows one through wine. There are other media managers too.
Actually after writing all this, i remembered you can just copy the image by right clicking the "Copy" option in the normal file manager and just "CTRL + V" the same way you would past text. Try here if you want and it also words for me on whatsapp,discord,lemmy. so i think it works on OS Level
like here. Treat it how you would treat any text
