Load image for image button

programming flash
1

I have a button object named “thumb1_mc”. In one layer, I put an empty movieclip “image_mc”.

I want to write actionscript 2.0 code to load a jpg into this movieclip.

I’ve tried …
loadMovie(“img/slide1.jpg”, _root.container.thumb1_mc.image_mc);

and I’ve tried …
var thumbClipLoader = new MovieClipLoader();
thumbClipLoader.loadClip(“img/slide1.jpg”,_root.container.thumb1_mc.image_mc);

both does not work.
