Can you use loadMovie in a tween?

Let’s say you have a movie clip with button states. The rollover and rollout sequences are tweens. Now let’s say you want to dynamically load jpgs into the buttons. You can use loadMovie to load the jpg into an empty holder clip on the button. But that will load it into the first instance of the holder clip, which is at the beginning of the tween. It disappears when you rollover and rollout.

How to get around this? :h:
