Getting image width on image load fails on IE

Question

I have a image resizer function that resize images proportional. On every image load a call this function with image and resize if its width or height is bigger than my max

Answer 1

getDisplay().getImage().setUrl(imgURL);
final Image img = new Image(imgURL);
int w=img.getWidth();
int h=img.getHeight();

Answer 2

I'd try this:

function onImageLoad(img, maxWidth, maxHeight) {
   var width, height;
   if ('currentStyle' in img) {
     width = img.currentStyle.width;
     height = img.currentStyle.height;
   }
   else {
     width = img.width;
     height = img.height;
   }
   // whatever
}

edit — and apparently if I were to try that I'd learn it doesn't work :-) OK, well "width" and "height" definitely seem to be attributes of <img> elements as far as IE is concerned. Maybe the problem is that the "load" event is firing for the element at the wrong time. To check whether that's the case, I would then try this:

function onImageLoad(img, maxWidth, maxHeight) {
   var width, height;
   var i = new Image();
   i.onload = function() {
     width = i.width; height = i.height;
     // ... stuff you want to do ...
   };
   i.src = img.href;
}
