I found some html code that allows pictures to be changed on a web page. I copied the code and saved it as an html file. when I click on it, my browser does display the pictures in sequence as it is supposed to using my Firefox browser. With Internet Explorer (version 8) it blocks the active-x unless I click on 'allow'. My question is why does this code get blocked automatically by Internet Explorer when I can view other web pages with Internet Explorer that have pictures changing on them and they do not get blocked?
