For copyright reasons, we only include information about pictures on official sites. Luckily, there are several official sites with pictures on them. The first URL has pictures of most of the important Muppets. henson.com has a nice section on Muppet charcters; click on "characters" in the lower-left corner of the main screen. The semi-official Kermitage can also help with Muppet Show muppets.
