I've been looking for a way to save #alttext for my images in a convenient place, so I can reuse it when I repost the image again / somewhere else. I've been using my website for that which is cool but not all my social images are on my website.
I just found out that you (obviously 🙄) can edit #exif #metadata with #Digicam (Ctrl-Shift-M) which then conveniently shows up in #Dolphin !
