Here's a little plugin to measure the original width and height of an image.
http://blog.softwareunity.com/2009/09/measure-raw-image-dimensions-using.html It has to pass the measurements to a callback so you use it like this: $("IMG").imgSize(function(size){ alert(size.width + "x" + size.height + "px " + size.fileSize + " bytes"); }); If anyone can think of a way to make it work without using a callback then let me know!
