That is the code you need to replicate. You can add as much as you like. You just make sure they are all in the parent container i.e the container with the slideshow className.

You add whatever figure you want and caption it. You can also add whatever image you want.

That will be great. I am still improving on my backend skills. I hope to build something great with the Steem blockchain too.
