Weird. It appears that, on my Mac, Firefox (1.0.6) doesn't have any sort of "copy image" command. The only options when right-clicking an image are:

- View Image
- Copy Image Location
- Save Image As
- Send Image As
- Properties

What's going on here? Both my Windows/Mac IE and Windows Firefox have a copy image command, and for the life of me I can't figure out why my Mac's Firefox doesn't.
