Don’t apologise… I had a “What?” moment myself. 
Yes, but it’s not delivered to the user as an .appimage; what would be the point? Otherwise it makes little sense to have an AUR project just to download an .appimage file. 
As said, the naming of the AUR project included “-appimage” probably to differentiate it from other digikam- projects on AUR.
Please try to clean up your last post.
Remove the picture, it’s not needed (be kind to the Server), and also remove those garbage characters from the pre-formatted text. Thanks.
By “garbage characters”, I mean ~, for example.
Nevermind, it’s taken care of.
