    [PHP & JavaScript] Image Gallery v2.0

    This is a modification of my original image gallery script. To use this script, just save it to a file index.php and place it in a directory containing images and you have yourself an image gallery.
    Example to call script
    Place index.php in folder http://yoursite.com/images/folder1
    an example link
    HTML Code:
    <a href="http://yoursite.com/images/folder1">Image Slideshow</a>
    There are four definitions that can be configured
    IMAGE_WIDTH - This sets the width of the image to be displayed in pixels
    THUMBNAIL_SIZE - this sets the width of thumbnails in pixels
    THUMB_MAX_HEIGHT - This sets the max height of the thumbnail window, if height exceeds max height then a scrollbar will be added
    THUMB_COLS - This sets the number of columns to use in the thumbnail section

    PHP Code:
