You can't get the width and height of the image just from the url(without some type of server side scripting).  The image would have to be loaded somewhere before you can tell how big it is.

However, you can load it in an absolute, hidden div and use offsetWidth/height to get the size of it.  This  is a quick example of how to get the image size, without actually showing the image.  You can add javascript to resize the image later or whatever.(tonberry.gif is a file of mine that is 339x300)

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript">

<style type="text/css">
	#imageloader
	{
		visibility: hidden;
		position:absolute;
	}
</style>
<title>Untitled Document</title>
</head>
 
<body>
<div><input type="button" value="Get Image Size" onclick="alert(document.getElementById('image').offsetWidth + 'x' + document.getElementById('image').offsetHeight) " /></div>
<div id="imageloader"><img id="image" src="tonberry.gif"></div>
</body>
</html>
