<?php

//usage: php envato-screenshots-downloader.php /path/to/save/screenshots http://url/to/screenshots/page 
set_time_limit(0);
$dir = $argv[1];

print_r($argv);
mkdir ($dir);
$src = file_get_contents($source);
$pattern = '/src="(https:\/\/0.s3[a-zA-Z0-9_\-\.\/%]+)"/i';
preg_match_all($pattern, $src, $matches);
foreach($matches[1] as $url){
	$url = str_replace(".__thumbnail","",$url);
	$url = str_replace("https","http",$url);
	$filename = basename($url);
	file_put_contents("{$dir}/{$filename}", file_get_contents($url));
	echo "Done {$url}\n";
}

No working for me !
Can you explain how to use ?
Thank you.
