Detecting _width / _height of loaded image

MX04

Is there a way to detect the _height and _width of a incoming image?

I’m going through a loop, duplicating movie clips with mask, loading an image, and squeezing it down to 100 x 100 for thumbnails. The client wants the thumbnails to be actual proportions but I used so many tweens and setup functions based on the 100 pixel width it’s going to be a nightmare.

Thanks!
