I used this code:
<a href="LINK"><img style="position:absolute; TOP:652px; LEFT:423px;" src="IMAGE LINK" /></a>
It's made the picture right where it needs to be when the window is maximized, but when I change the window size it stays 423px from the left side of the screen. I was wondering how to change the positioning of the image to be from the center of the page instead of from the left of the page.
