Answer 3

Taking KPrimes great answer and adding in trackers suggestion, this is what I came up with:

jQuery(function($) {
    // we have both a image and a refresh image, used for captcha
    $('#refresh,#captcha_img').click(function() {
       src = $('#captcha_img').attr('src');
   // check for existing ? and remove if found
       queryPos = src.indexOf('?');
       if(queryPos != -1) {
          src = src.substring(0, queryPos);
       }    
       $('#captcha_img').attr('src', src + '?' + Math.random());
       return false;
    });
});

You can force a refresh by appending a random string at the end, thus changing the URL:

$('#verifyimage').click(function() {
    $(this).attr('src', $(this).attr('src')+'?'+Math.random());
});
