Yeah that's a pretty clever solution.

About the "fixed" in Opera, to be sure I'll explain it again:

1) The viewport != 400x300 DIV with overflow:auto;

2) Fixed and scroll are in regard with the viewport.

3) Firefox/Opera/the rest are doing it right with scroll. IE is wrong.

4) Resize the windrow until you can scroll the browser scrollbars. When you scroll, the image will scroll along with the box/content/everything inside. Version 1.
