* 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!
