I am not really good with JavaScript, and I am trying to make a site for my friend's business. I am making like a comic book website for him, he draws. He would like to have like characters from his story pop out randomly for 30 seconds but just the picture's popping out the side and randomly change. So like you on the site and from the middle right it just opens up for 30 seconds, closes and 2 minutes later a different picture of a different character comes out. This might be already done for a site but I can not find anything like this and I certainly am not creative enough to think how to do it.
