upload billede

Jeg er ved at modificere det chat script der hedder 1906_MiniChat3-1.. og have at man skal kunne uploade et billede af sig selv på sin egen profil.

selve *user profile* siden ser således ud:

<?
require("config.php");
require("funktioner.php");

$brugerinfo = brugerinfo($_COOKIE[minichat3_id]);
checksession($brugerinfo[sesid]);

$normal = "#eeeeee";
$hover = "#dddddd";

if ($_POST[action] == "update"){
    $free_text = format($_POST[free_text]);
    $free_text = nl2br($free_text);
    $email = htmlentities($_POST[email]);
    $age = format($_POST[age]);

    mysql_query("UPDATE chatuser SET free_text='$free_text',email='$email',age='$age' where id='$brugerinfo[uid]'") or die (mysql_error());
    WriteToRemote("",$brugerinfo[id],"Your userinformation has been updated!");
    header("Location: top.php");
}
?>
<HTML>
<HEAD>
<link rel="stylesheet" type="text/css" HREF="style.css">
</HEAD>
<BODY>
<br>
<?
if ($_GET[action] == "edit"){
?>
<table width="70%" border="1" cellspacing="0" cellpadding="0" bordercolor="#000000" align="center" CLASS="alm-text">

</table>
<? } ?>
<br>
<div align="center" CLASS="alm-text"><a href=\"java script:top.close()\">Close</a></div>
</BODY>


så det jeg har brug for er et felt/link med *Upload Image*
med:
/browse funktion
/max 30kb size
/et *standart* billede hvis brugeren ikke har uploadet billede
/og evt. admin godkendelse af billedet ( dog ikke vigtigt)

jeg ved ikke om jeg skal bruge mySQL database til at holde styr på billederne eller hvordan?..

Håber i kan hjælpe!!
