Description of problem


I put the JavaScript from this topic https://help.forumotion.com/t144239-turn-your-forum-banner-into-a-slide-show in my forum.

Code:

        (function() {
          var BannerRotator = {
            images :  [ 'http://upic.me/i/7p/ebi01.jpg',
'http://upic.me/i/x5/3h021.jpg',
'http://upic.me/i/ln/i6w03.jpg',
'http://upic.me/i/jv/3o204.jpg',
'http://upic.me/i/rq/lkv05.jpg',
'http://upic.me/i/2x/7copycopy.jpg', ],
       
            start_delay : 5000,
            duration : 5000,
            height : 'auto',
       
            fade_image : true,
            fade_speed : 1200,
         
            keep_initial : true,
            remember_position : true,
            preload : true,
       
            // technical data below
            index : -1,
            logo : null,
         
            // increment the index and display the next image in rotation after a small delay
            next : function(ms) {
              if (ms === undefined) ms = FA.BannerRotator.duration;
       
              window.setTimeout(function() {
                if (++FA.BannerRotator.index >= FA.BannerRotator.images.length) FA.BannerRotator.index = 0; // reset index when it exceeds "images" length
                if (FA.BannerRotator.remember_position) my_setcookie('fa_banner_index', FA.BannerRotator.index); // remember the last banner shown
             
                // fade banner in and out
                if (FA.BannerRotator.fade_image) {
                  $(FA.BannerRotator.logo).fadeOut(FA.BannerRotator.fade_speed, function() {
                    FA.BannerRotator.logo.src = FA.BannerRotator.images[FA.BannerRotator.index]; // set next banner
                    $(this).fadeIn(FA.BannerRotator.fade_speed, FA.BannerRotator.next); // fade it in
                  });
                }
       
                // default rotation
                else {
                  FA.BannerRotator.logo.src = FA.BannerRotator.images[FA.BannerRotator.index];
                  FA.BannerRotator.next();
                }
              }, ms);
            },
         
            // initial start up to get the correct logo node and setup some other settings
            init : function() {
              var logo = document.getElementById('i_logo') || document.getElementById('logo') || document.getElementById('pun-logo'),
                  index = my_getcookie('fa_banner_index');
               
              if (logo) {
                FA.BannerRotator.logo = logo.tagName == 'IMG' ? logo : logo.firstChild;
                FA.BannerRotator.logo.style.height = FA.BannerRotator.height;
             
                if (FA.BannerRotator.keep_initial) FA.BannerRotator.images[FA.BannerRotator.images.length] = FA.BannerRotator.logo.src;
                if (FA.BannerRotator.remember_position && index) {
                  FA.BannerRotator.index = +index;
                  FA.BannerRotator.logo.src = FA.BannerRotator.images[FA.BannerRotator.index] || FA.BannerRotator.images[0];
                }
             
                FA.BannerRotator.next(FA.BannerRotator.start_delay);
              } else if (window.console && window.console.warn) {
                console.warn('Your forum version is not optimized for this plugin');
              }
            }
          };
       
          if (!window.FA) FA = {};
          if (!FA.BannerRotator) {
            FA.BannerRotator = BannerRotator;
         
            if (FA.BannerRotator.preload) {
              for (var i = 0, j = FA.BannerRotator.images.length, img; i < j; i++) {
                img = document.createElement('IMG');
                img.src = FA.BannerRotator.images[i];
              }
            }
         
            $(FA.BannerRotator.init);
          }
        }());

it works. but when I scroll down to bottom, the scrollbar will jump up, It happens with every page which I use this javascript and I don't know how to solve. pls help me, Thanks

ps. now I use this javascript in the homepage and sub-forum (because I don't want to annoy my members by auto-jump scrollbar in all topics) however, I would like to use it in all the pages of my forum.
