ahh well i did actually explore this long ago for A LONG time
here is a function using fsockopen it will see if the file exists on the
server given
it returns $status FALSE or TRUE
if TRUE then file exists

function get_headers($URL)
{
$URL2 = eregi_replace("http://","",$URL);
$splitURL = split("/",$URL2,2);
$host = $splitURL[0];
$path = $splitURL[1];

if((eregi("\.",$host)))
{
$gh = fsockopen ("$host", 80, &$errnr, &$errstr) or die("$errno: $errstr");
$hpath = "/".$path;
fputs($gh,"HEAD $hpath HTTP/1.0\n\n");
$line = fgets($gh, 15);
if(eregi("200 OK",$line))
{
$status=TRUE;
return $status;
}
else
{
$status=FALSE;
return $status;
}
}
}
