viking - separately from the option to Edit attributes for all files in directory, you can actually edit the attributes of the directory itself, as if it were a file as well. Instead of clicking on the directory in the left hand pane to display its contents then clicking on the file in the right hand pane to edit its attributes .... you can navigate up the directory structure, and when you see the directory itself listed in the _right hand pane_ click on it there instead of clicking on it in the left hand pane. Now you will see the attributes of the directory in the right hand pane instead of the directory's contents. You can now set cover art for the directory.
