If allow_url_fopen[1] is enabled:
<?php

$url = 'http://example.com/image.jpg';
$savedir = '/tmp'; //or anything else you want
$overwrite = true; //or false if image has to be renamed on duplicate

$urlinfo = parse_url($url);
$filename = basename($urlinfo['path']);
$target = $savedir.'/'.$filename;
if(file_exists($target) && !$overwrite){
//break up file in parts:
$pathinfo = pathinfo($target);
//max 50 tries
$max = 50;
//loop
for($i = 1;$i<=$max;$i++){
$target = $pathinfo['dirname']. '/' . $pathinfo['filename'] . '[' . $i
.. '].' . $pathinfo['extention'];
//break on success, do not use file_exists to avoid race
$fh = @fopen($target,'x');
if($fh) break;
}
//alternatively, if you don't care about the name, you can just:
//$target = tempnam($savedir);
if(!$fh) die('Too many retries, no unique filename found.');
} else {
$fh = fopen($target,'w');
}
$check = fwrite($fh,file_get_contents($url));
fclose($fh);
echo (($check) ? 'Successfully saved '.$target : 'Failure');
?>
