i had stored my images on a password protected folder, inorder to protect it from downloading. how can i use that images on my site?
You shouldn't put your images in a password protected folder but in a folder with a .htaccess mod-rewrite script that checks if the referer is allowed (so it checks if the visitor is on your site). If the visitor is not allowed you can show another deny image instead. This script generator seems to be doing that: http://isnoop.net/dev/mod_rewrite.php
