Clear an image preview file that was removed from the array with jquery

Question

I tried to figure this out for over a month now. I cannot get the image to be removed from the array once the image was clicked on 'x' on the previewer.

http://jsfiddle.net/ERZVC/2/

My attempt to use splice failed!

$('#list').on('click', '.remove_img_preview',function () {
        $(this).parent('span').remove();

        //this is not working...
        var i = array.indexOf($(this));
        if(i != -1) {
            array.splice(i, 1);
        }
        // tried this too:
        //$(this).parent('span').splice( 1, 1 );

        count--;
    });

please help me out!
