Width according to loaded img?

Pixeladdict · April 14, 2006, 10:57am

Im loading in some images (all with 50px in height), with various widths.
I have an animation over the images in a MC called “over”.
the MC over lies within thumbMC wich again lies within a MC called containerMC.

ThumbMC is generated as many times as I have images (via XML)

The image loaded in gets loaded in “loader” which lies within thumbMC aswell.

Id like “over” MC to be the width of the loaded image.

heres the AS for the scroller I have all the thumb images scrolling in:
