                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
                                                <?php    // this will looping  image background custom - xx_rusly_xx
                                                    $images = getFieldOrder('background_slideshow_image');
                                                        foreach($images as $image){
                                                            echo "{image : '";
                                                            echo get('background_slideshow_image',1,$image);
                                                            echo "'},";
                                                        } 
                                                ?>
                                            ]                           
            }); 
        });

    </script>

If u see i put some php code for loop image url

<?php    // this will looping  image background custom - xx_rusly_xx
$images = getFieldOrder('background_slideshow_image');
    foreach($images as $image){
        echo "{image : '";
        echo get('background_slideshow_image',1,$image);
        echo "'},";
    } 
?>

and browser will generate javascript with php like this :

//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://iconcept-project.com/dev/gd/wp-content/files_mf/1.jpg'},
        {image : 'http://iconcept-project.com/dev/gd/wp-content/files_mf/2.jpg'},
        {image : 'http://iconcept-project.com/dev/gd/wp-content/files_mf/3.jpg'},
        {image : 'http://iconcept-project.com/dev/gd/wp-content/files_mf/4.jpg'},                                                                                                                   ]                           
    }); 
});         
</script>

and the problem is how to remove comma in last line, because with internet explorer this will not run except i remove the last comma.

{image : 'http://iconcept-project.com/dev/gd/wp-content/files_mf/4.jpg'},

here is full code –> http://pastebin.com/c1A7ZKGr

I’m curious. Why don’t you do that in PHP side?

<?php    // this will looping  image background custom - xx_rusly_xx
$images = getFieldOrder('background_slideshow_image');
    foreach($images as $ind => $image){
        echo "{image : '";
        echo get('background_slideshow_image',1,$image);
        echo "'}".($ind == count($images)-1 ? '' : ','); // no comma for last image
    } 
?>
