Images are loaded by a separate Thread so you can not immediately get the width and height. A MediaTracker will help you there.
You can NOT put an image into a page from inside a JSP, all you can do is write the code that makes the browser load the image - look at the html tag for <img> - it takes a URL because the browser starts a separate Thread to load the image.
