Image Physics Question

I am having a problem with my images, and dont understand how to fix it.

I am playing around with an image of the little green man - Jumping, detecting collisions, and such.

Here is my question, at one point my image falls over, and this is confusing to me,.
I know its because its a physics body. How to I get the image to stay positioned up right.

Also see that the images seem to be touching correctly when the image is up right but notice how the little green man seems to be sitting in the air after he falls over in the second image.

I think i fixed the part about not letting my man fall over, i set

instance2.isFixedRotation = true so now he seems not to rotate at all - which is good. But can anyone explain why part 2 of my images would occur? [import]uid: 11860 topic_id: 4427 reply_id: 13797[/import]
