Header image size

[tropicsbear]

First post for 2012!

So I'm trying to edit the layout I'm currently using. I tweaked some of the original CSS to accomodate my new header. I set the height to 200px since the image height is exactly 200px. But I noticed that there seems to be an extra few couple of pixels and that my header repeats.

This is the relevant CSS:

#header {
background:url("http://a.random-image.net/bcdmonte/batman.jpg") repeat scroll 0 0 transparent;
border:2px dashed #2D231C;
height:200px;
text-align:right;
}

I tried removing repeat scroll 0 0 transparent from the CSS but that just resulted in the entire header (plus the border) to disappear. Help?
