HTML and backgound height?! Options

[GunsNRachel]

I'm trying my hand at HTML today, and I can't figure out how to change the background images height. My code for the background looks like this:

CODE

<center>
background-color: #F9F8D7;
background-image:url(http://i6.tinypic.com/5yd2gkg.png);
background-repeat: repeat-none;
margin: 0px;
scrollbar-base-color: #000000;
scrollbar-track-color: #000000;
}

What do I need to change?

I have another question! I figured this one out =)

Alright so I'm trying to make an image map. I did it in image ready and copied the html code:

CODE

<img src="http://i6.tinypic.com/5yd2gkg.png" width="1009" height="768" border="0" alt="" usemap="#TMA2_Map">
<map name="TMA2_Map">
<area shape="rect" alt="" coords="257,273,751,751" href="http://takemeawaylayouts.bravehost.com/Index.html">
</map>

It won't work though! What do I do? Where do I put it?
