title: Determining image file size + dimensions via Javascript?
body: <p>As part of a web app, once images have been downloaded and rendered on a web page, I need to determine an image's file size (kb) and resolution within the browser context (so I could, for example, display that info on the page. This needs to be done client-side, obviously. Must be able to be solved x-browser without an ActiveX control or Java applet (IE7+, FF3+, Safari 3+, IE6 nice to have), though it doesn't have to be the same solution per browser.</p>
  
  <p>Ideally this would be done using system Javascript, but if I absolutely need a JQuery or similar library (or a tiny subset of it), that could be done.</p>
