The code itself is self descriptive. If you still don’t understand how it works, then plz shoot me a comment.

Most probably I will get back to you :)

/**
 * Directory2Gallery - Gallery maker
 * Do you need to create photo gallery from all the images recursivley kept in
 * different folders? Do you like to filter those files? Well, you can do it rite away!
 * just copy this index.php file and paste it in your desired location. Point your browser to it
 * And see the fun!!
 *
 * This file contains some code used only when you drop this file in any folder to access the
 * folder for viewing as gallery. Optionally you may use jQuery tools overlay or something
 * like that to add overlay effect. Owh by the way NO HTACCESS IS REQUIRED!

    line 79 have to and the Tag and not open a new one.

    and if your php version did not support the function “mime_content_type” you can easily commend this line out and the script will work
