i use exact this code:
body
{
background-image:url('gradient2.png');
}
found on w3 school its simple i got the pic in same folder, i did everything and i dont know why i cant insert images in css. The html tag is working. I had the same problem 3-4 months ago, and now working again with html and still, not working. The pic just wont show.
this is my full css:
*
{
    margin: 0;
    padding: 0; 
}
body
{
        background: url("pagebg2.jpg") repeat left top;    
    font: normal 10pt Arial,Helvetica,sans-serif;
}
#center{
    box-shadow: 1px 1px 11px 1px rgba(0, 0, 0, 1);
    border: 3px solid rgba(0, 0, 0,0.8);
    background-color:#50649d;
    border-radius: 20px 20px;
    width: 650px;
    height:900px;
    margin: 0 auto;
}
#pic {
     text-align:center;
}
img {
    box-shadow: 1px 1px 11px 1px rgba(0, 0, 0, 1);
    border: 3px solid rgba(0, 0, 0,0.8);
    border-radius: 20px 20px;
}
and this is the html:
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <link type="text/css" rel="stylesheet" href="CSS/btstyle.css">
        <title></title>
    </head>
    <body>
        <header>this is the title</header>
        <div id="container">
                <div id="pic" class="column">
                <img src="opel.png" />
                </div>
                <div id="center" class="column">
                  center
                </div>
        </div>
        <footer class="foot"><p>©WebMaster pr.toma@gmail.com</p></footer>
