javascript to run after browser has scrolled to url fragment

I have the following code deep within a webpage:

<div id="123">

When a user navigates to http://ift.tt/1M5jgRK the browser will automatically scroll to the div position due to the fragment "#123".

I want some javascript to run after the browser has scrolled to the div position (so I can the change the position by 111px)

The webpage also has lots of images which take a while to download, and the browser scrolls before these images are all downloaded - which is good.

So, I can't use the window.onload event as this won't run until all the images are downloaded.

The javascript I want to run after the browser has scrolled to the div is below. This works fine in Chrome but not in IE:

    window.setTimeout(
        function () {
            var scrollTop = $(window).scrollTop();
            $(window).scrollTop(scrollTop - 111);
        }, 0);
