Load image size

I’m trying to import images into a movieclip and I used this Kirupa tutorial to help me: http://www.kirupa.com/developer/flashcs3/loading_image_as3_pg1.htm

I now have the image loaded but was wondering how to resize it using actionscript 3. I am sort of new to actionscript, but know some basics so as much help as I can et would be appreciated.

Thank you.
