reference point and empty movie clips

Hi =)

I have an empty movie where i load some content (images), but i need the reference to be on bottom right of the content, while flash load the content with reference point at top left =(.

Any clues of what can i do?

I think that it is possible to change reference point with as2, but i'm not really sure how and if it's the best solution.

Thanks =)
ps: working with as2 and flash player ver. 9 on flash cs3.

Are you dynamically creating the movie clip using AS code, or do you have the movie clip on the stage?

I have the movie clip empty on stage =)

Use the image loader component instead of using empty movie clips.
