When you right click on the flipbook, click on properties. You should then see a URL code. Copy and paste that.
I did what you said but when I put the URL in the Enter URL box it just showed the first picture of the flipbook. It didn't show the other pictures in the flipbook.
Well i take take screen shots from babv. Then i go to www.iconator.com and click on iconator animater and then you just pick the pictures and it animates them for you.
