just my 2 cents, but ...once you created an animation using Poser Physics, you could then go back & select images from possibly hundreds of stills (depending on how long your animation was),, but also via the PoserPhysics animation you would wind up with eventually tons of free poses which you could save to your Pose library (& as another plus, most all of the poses would be poses that you probly wouldn't be able to buy because they would be unique or created from your own animations)
