$url is the full URL address of the remote picture and cannot be empty.
$filename is an optional variable: If NULL, local file names are based on time and date
Automatically generated.

function Grabimage ($url, $filename = "") {
if ($url = = ""): return false;endif;

if ($filename = = "") {
$ext =STRRCHR ($url, ".");
if ($ext!= ". gif" && $ext!= ". jpg"): return false;endif;
$filename =date ("Dmyhis"). $ext;
}

Ob_start ();
ReadFile ($url);
$img = Ob_get_contents ();
Ob_end_clean ();
$size = strlen ($img);

$FP 2= @fopen ($filename, "a");
Fwrite ($fp 2, $img);
Fclose ($fp 2);

return $filename;
}

$img =grabimage ("Yun_qi_img/000003.png", "www.111cn.net.png");
