icon for asl.options (SB1 html based app development)

Hi All,

Is there anyway i can include image for the asl.options?

asl.options([                   

{

                        'title': 'My Info',

                        'icon': 'loading1.png', // something like this..

                        'callback': asl.exit

                    },]);

Many thanks in advance,
