No... you cant.
What you can do is make your own icons. Its really easy, you take the picture you want make it 90 by 90 in paint and save it as a .ico file. Then you can select it when you click change icon to this.
I hope someone can help me. I'm wanting to use a photo for a desktop folder, instead of an icon. I've clicked on the folder, gone to properties, and than to customize, but I can only do a photo on the folder for thumbnail views. Is there some other way of using photo's to ID my desktop folders?
I was thinking of makiny my own icons, but not too sure on how to do that.
Thanks for any and all help.
