Moving or deleting the cover image of an album is not possible

[frederikb96]

When moving or trying to delete the cover image of an album, most of the time this does not work.

E.g., trying to delete multiple images of an album, where one of the images is the cover image, results in the deletion of all selected images except for the one that is the cover image.

I would like to propose two possible solutions to this problem:

1. Also delete the cover image and assign another image which is still present in the album to be the new cover image. If there is no image left in the album, display the album without any cover image and without any images left or simply delete the album after asking the user if that should be done.
2. Or simply show a message to the user that the cover image cannot be deleted and keep everything else like it is.

I would go with solution 2.
