• Answer:

  All the variables are at the top = upload_url: "upload-file.php", file_post_name: 'uploadfile', file_size_limit : "4096", file_types : "*.jpg;*.png;*.gif", file_types_description : "Image files", file_upload_limit : 100, flash_url : "js/swfupload/swfupload.swf", button_image_url : 'js/swfupload/wdp_buttons_upload_114x29.… button_width : 114, button_height : 29, button_placeholder : $('#button')[0],
