Okay I am a significant newbie only at that but here goes:

I am using supersized.js using blogging platforms site to produce full-sized background image slideshows for that top of the page suffice to express the script is setup and it is working now my next problem ended up being to result in the script pull the pictures using wp_attachment

During my functions.php file I produced this:

// Get all of the images attached to the current post
// These images will be used in the Supersized homepage gallery
function supersized_get_images($size = 'full') {
    global $post;

    $photos = get_children( array('post_parent' => $post->ID, 'post_status' =>     'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID') );

    $results = array();

    if ($photos) {
        foreach ($photos as $photo) {
        // get the correct URL for the selected size
        $results['image'] = wp_get_attachment_url($photo->ID);
    }
}
// encode into JSON format and pass to javascript supersettings.js
echo json_encode($results); 
}

So anyway (I place the echo) in because I needed to determine it was creating the right JSON format. The output on echo appears like this:

{"image":"http:\/\/pilarcorrias.secondvariety.org\/wp-content\/uploads\/0bcf5aa159739b260a77758c7d33699b.jpg"}

This I am presuming is appropriate. Supersized includes a setting file that appears such as this:

jQuery(function($){
            $.supersized({

                //Functionality
                slideshow               :   1,      //Slideshow on/off
                autoplay                :   1,      //Slideshow starts playing automatically
                start_slide             :   1,      //Start slide (0 is random)
                random                  :   0,      //Randomize slide order (Ignores start slide)
                slide_interval          :   3000,   //Length between transitions
                transition              :   1,      //0-None, 1-Fade, 2-Slide Top, 3-Slide Right, 4-Slide Bottom, 5-Slide Left, 6-Carousel Right, 7-Carousel Left
                transition_speed        :   500,    //Speed of transition
                new_window              :   1,      //Image links open in new window/tab
                pause_hover             :   0,      //Pause slideshow on hover
                keyboard_nav            :   1,      //Keyboard navigation on/off
                performance             :   1,      //0-Normal, 1-Hybrid speed/quality, 2-Optimizes image quality, 3-Optimizes transition speed // (Only works for Firefox/IE, not Webkit)
                image_protect           :   1,      //Disables image dragging and right click with Javascript
                image_path              :   '/../../../slideshow/', //Default image path

                //Size & Position
                min_width               :   0,      //Min width allowed (in pixels)
                min_height              :   0,      //Min height allowed (in pixels)
                vertical_center         :   1,      //Vertically center background
                horizontal_center       :   1,      //Horizontally center background
                fit_portrait            :   1,      //Portrait images will not exceed browser height
                fit_landscape           :   0,      //Landscape images will not exceed browser width

                //Components
                navigation              :   1,      //Slideshow controls on/off
                thumbnail_navigation    :   1,      //Thumbnail navigation
                slide_counter           :   1,      //Display slide numbers
                slide_captions          :   1,      //Slide caption (Pull from "title" in slides array)
                slides                  :   [       //Slideshow Images
                                                    {image : 'http://buildinternet.s3.amazonaws.com/projects/supersized/3.1/slides/quietchaos-kitty.jpg', title : 'Quiet Chaos by Kitty Gallannaugh', url : 'http://www.nonsensesociety.com/2010/12/kitty-gallannaugh/'},  
                                                    {image : 'http://buildinternet.s3.amazonaws.com/projects/supersized/3.1/slides/wanderers-kitty.jpg', title : 'Wanderers by Kitty Gallannaugh', url : 'http://www.nonsensesociety.com/2010/12/kitty-gallannaugh/'},  
                                                    {image : 'http://buildinternet.s3.amazonaws.com/projects/supersized/3.1/slides/apple-kitty.jpg', title : 'Applewood by Kitty Gallannaugh', url : 'http://www.nonsensesociety.com/2010/12/kitty-gallannaugh/'}  
                                            ]


            }); 
        });

The final line within this file declares the parameter slides after which passes image references towards the slideshow. Now I have checked and also the slideshow functions perfectly well with no URL and TITLE information, meaning I only have to provide the image object which this is actually the file URI meaning my little bit of JSON should work verbatim. Since I understand I'm encoding the PHP array properly how do you have it in to the supersettings.js file above... been looking everywhere although not found something which describes it in ways I'm able to get my small brain around. Any help could be much appreciated.
