On my background, whenever I set something to `position:absolute;` It disappears, but not when I set it to `position: relative;` 

Any thoughts? Not really urgent, I can work with position relative, just curious. (Note: I know the picture has `style="display:none;"` in it but that doesn't matter, I change that with a function, so ignore it)

Picture:

```
<img src="http://i39.tinypic.com/15qvslj.jpg" style="top: 375px; left: 400px; position: relative; z-index: 1; visibility: show; display:none" id="Controls">

```
