Exporting individual pages with gifs as animated gifs

I normally use the command Publish and share the presentation with my clients, but I would like to put some of those pages up on my website, to show my portfolio. The problem is that I can't figure out how I could export the pages as independent animated gifs so that I can put those images up on the website. What I'm trying to do is something like this:

Hopefully, you can help, because I'm going bananas.
