If you need to optimize the images for your existing website, the following code might be useful:
<?php $dir = '/home/some_directory/'; // the directory with your files $compr = 80; // the quality precentage if ($handle = opendir($dir)) { while (false !== ($file = readdir($handle))) { $path = $dir.$file; if (is_file($path)) { $ext = pathinfo($path, PATHINFO_EXTENSION); if (preg_match('/^(jpg|jpeg)$/i', $ext)) { exec(sprintf('convert %s -quality %d %s', $path, $compr, $path)); } } } closedir($handle); } ?>
Just enter the path to the the directory you like to optimize safe the code as a PHP script and execute the file from the command line of browser.
Optimize your images top make them load faster, but be careful don’t compress them too much.
