Jared, Jensen, and Misha icons. One is animated. A few of these I use myself but they are shareable so I thought I'd post them all.
Pic sources: Joits @ flickr.com, WB, Michael Muller (pic in animated icon), DreadCentral.com, saltedandburned.com (if I'm missing any, please let me know!)
Comments are love. If you take any, credit is always appreciated. :)
