Make Image Container Div Fit Nicely Around Image

I am preloading some images, so prior to the downloading I have:

In Mozilla: initially WxH = 0x0 ... after img downloaded WxH = good# x good# the div just stretches just the right amount to fit snuggly around the newly loaded image;

But the other browsers do different things;

My current solution, which works, uses a new Image().width approach where I manually resize the container div;

How to get the other browsers to automatically resize the container divs;
