Couldn't get that one to work for some reason? But the one below might be more simple.
Cut & paste the script into notepad & Just change the image url's to your own & also the times (marked in red). Also add your images to the page using the BV file uploaded as they will then stay in the same directory. Then just cut & paste the script from notepad to a html box on your BV page.
