Summary: new DynImage('src') does not always find src in loadimages

Details: When you create a new DynImage from a path, it checks the
loadimages array for an image with the that path that exists
already. i've been creating dynimages by passing an
absolute path to the image without the host part. because the browser adds
the host to src in the image object, when i create a new dynimage from the
same path my
image is not found in loadimages array.

here's an example:
myImage1 = new DynImage('/images/button.gif');

Now DynImage.loadimages has one image in it.

myImage2 = new DynImage('/images/button.gif');

DynImage.loadimages now has 2 images in it, because
when it was looking for '/images/button.gif' it only
found 'http://hostname/images/button.gif'

I modifed DynImage.getImage to fix the problem. It seems to work, here's my
new function:

DynImage.getImage=function(src,w,h) {
	for (var i=0;i<DynImage.loadimages.length;i++) {
		if (DynImage.loadimages[i].img.src_orig==src) {
			return DynImage.loadimages[i].img;
		}
	}
	DynImage.loadimages[i] = {};
	if (w&&h) DynImage.loadimages[i].img = new Image(w,h);
	else DynImage.loadimages[i].img = new Image();
	DynImage.loadimages[i].complete = false;
	DynImage.loadimages[i].img.src=DynImage.loadimages[i].img.src_orig=src;
	return DynImage.loadimages[i].img;
};
