CSS image placement problem?

[Future Sailor]

I can't figure out why this works in Internet Explorer and not Firefox 3. It adds "repeat scroll 0 0;" and I never added that in the code.

Here's the CSS code:

/*
CSS for Victory Sports Site
*/


body {
font-family: Verdana, Helvetica, Arial, sans-serif;
background: url(backgrounds/vbs sports/vcs logo/DSCN4949.JPG) ;
line-height: 125%;
padding: 0;
margin: 0;
}


img {
border: 5px inset black;
padding: bottom 5px;
left: 296px;
right: -167px;
top: 179px;
bottom: -42px;
float: right;

}

h1, h2, h3 {
font-family: "Trebuchet MS", Helvetica, Arial, sans-serif;
}


h1 {
font-size: x-large;
color: white;
padding-top: 2em;
padding-bottom: .2em;
padding-left: .4em;
margin: 0;
background: url(sportssite/backgrounds/sportsheader.jpg);
}
