Inserting an image based on a selection

Hi

I'm developing my first rails application and would like advice on how
to show a small image in a table cell based on a selection. This will
be based on a user selecting a Risk score from a select or check box

#2

onchange of a select box you can use remote_function to call an action
and user replace_html or on your rjs file to replace the html to show
the jpg

Thanks for the advice Sami

In case anyone else is trying to do something similar, here is the jquery code I used -

  $('div.risk').each(function() {
    var value = $.trim($(this).text());
    var src;
    switch(value) {
        case 'Critical':
            src = '/images/risk_high.png';
            break;
        case 'Medium':
            src = '/images/risk_med.png';
            break;
        case 'Low':
            src = '/images/risk_low.png';
            break;
        case 'Information':
            src = '/images/risk_info.png';
            break;                  
    }
    $img = $('<img/>').attr('src', src);
    $(this).html($img);
});
