Here’s a little experiment to take a wire frame man and make him walk. Each part, such as thighs and calves, forearms and upperarms, etc, affect the other parts of the body.
The head bob is a bit much especially at high speeds, but otherwise, I think it works ok. You should be able to replace the lines with images of body parts to acheive a decent walking animation. You can see a working example at http://www.geocities.com/webwizardsways/images/walking.swf (the slider affects the speed, right is faster, left is slower)
