Loaded MovieClip Width

Hi:

I have to load some pictures (jpg) and movies (swf) to a MovieClip. But to properly locate the MovieClip I need to know the width and height of my picture or movie(they don´t always have the same measures).

I´ve tried to get it just after I loaded the picture or movie but the data I´ve got is that of the previous picture or movie loaded.(In the first object load I get 0). So, the one I´m loading is not quite centered in the MovieClip.

Is there a way to get the width and height of the object I´m loading?

Thanks for your time and very helpful this page to save time looking for some answers.

Regards,

Lenna
