Onload callback for dynamically loaded images
Sometimes you need to dynamically load an image and do something as soon as its loaded (when for example its size is already available).
With jQuery, this seems to work across browsers:
$('<img>')
.attr('src', '')
.load(function() {
alert('fully loaded!');
})
.attr('src', '/the/real/image/url');
