Hi!

I'm working with images, and if I don't specify an width and height to an
image it fits the exactly size of the image (didn't tested for images larger
then the screen).

What I would like to do is get the width of this loaded image, so I can
calculate to put it in the center of the screen with (screen/width/2 -
image.width/2),
any idea how to get loaded image's width?

Trying with:

var image = getElementById('loadingImage');


image.width returns nothing..
