A long time ago I used to edit my pets a bit with a scarf or something and just overlay an image over the original with this code:
<div style="overflow: auto; width: 265px; height: 240px; position: absolute; top: 491px; left: 268px; border:none; background-color: transparent; padding: 2px; color:white;"><img src="http://i41.tinypic.com/2lu860x.jpg"></div>
However, I want to use it for a different purpose now- sort of just a little image that stays in one corner of the screen without moving even when you scroll. How do I make it so that it stays locked in place?
