Make a windows folder icon have an image or photo appear over it in the Thumbnails view.

This tip is especially useful to use with folders that contain your MP3 or iTunes music files like this example at Paul Thurott’s site. When you view the folder in the Thumbnails view, they will have a photo over the folder. You can include the album art for each folder of your music files.

To do this, just place the image you wish to appear for that folder within that folder and name the image folder.jpg.

Now whenever you are looking at your folders with the selection enabled under VIEW–>THUMBNAILS, that folder will appear with that image over the folder.
