I made this for bringing back and improve the XP-appearance of my music collection: Using album cover (folder.jpg) as folder icon.
ATTENTION: The .directory-file will be rewritten with Icon-Entry only.
extract the archive to: ~/.kde/share/kde4/services/ServiceMenus
It contains two files:
UseFolder.jpg.desktop: works on any folder; will set a containing folder.jpg as folder icon; also works with marking multiple folders
UseAsFolderIcon.desktop: works on any graphic file; will set an image as icon for the folder, where it is located
