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

This is how I solved it (because it's the only js on the site I didn't want to use a library).

    var imageElement = document.createElement('img');
    imageElement.src = el.href; // taken from a link cuz I want it to work even with no script
    imageElement.style.display      = 'none';

    var imageLoader = new Image();
    imageLoader.src = el.href;
    imageLoader.onload = function() {
        loaderElement.parentElement.removeChild(loaderElement);
        imageElement.style.position     = 'absolute';
        imageElement.style.top          = '50%';
        imageElement.style.left         = '50%';
        // here using the imageLoaders size instead of the imageElement..
        imageElement.style.marginTop    = '-' + (parseInt(imageLoader.height) / 2) + 'px';
        imageElement.style.marginLeft   = '-' + (parseInt(imageLoader.width) / 2) + 'px';
        imageElement.style.display      = 'block';
    }
