loadMovie issue

Hello.

I am trying to load an image into an empty movie and have it centered within a frame… however the loadMovie function will load my image using the dot (register point) of my empty movie as the upper left corner … this is fine so far… however i cannot obtain the size of the image loaded … so how can i center it within my frame ?

_width on my empty movie with the loaded image into it returns 0 ?

So what is the solution … once I load the image into my empty movie, how can i center it within my frame … or any other object ?

thank you
