// Folder where source images are stored (thumbnails will be generated from these images).
// MUST end with slash.
$images_folder = 'www/images/';

// Folder to save thumbnails, full path from the root folder, MUST end with slash.
// Only needed if you save generated thumbnails on the server.
// Sample for windows: c:/wwwroot/thumbs/
// Sample for unix/linux: /home/site.com/htdocs/thumbs/
$thumbs_folder = 'www/thumbs/';
