Kindle Vella is the NEW service and story telling option by Amazon/KDP. Authors can publish serialised stories, one short episode at the time. Unfortunately, at this stage this service is only available to US based authors. You can find more information here:

Like other eBooks, you also need covers for your stories. Of course, because you don’t need text on the cover you could use any licensed stock image or do a design yourself, but to stand out you should think about a professional designed and unique design. Even if the image is small, it is important to show the reader what kind of book and genre they expect.
From August I offer custom Vella covers for $50, if the design is made out of a bought premade cover or $100, if it is a complete new design. I don’t do premade Vella covers. Contact me, if you are interested.
Book Advertising Guidelines and Acceptance Policies
Not only the cover designer, also the author should know what Amazon does or doesn’t accept for AMS Ads. AMS guidelines change all the time. Sometimes things are allowed, sometimes not. Here are the official rules: ADVERTISING RULES AND GUIDELINES
Part of my custom service is a 3D mockup image for each custom book cover. From July I also offer a professionally created GIF with the background matching the book, the book itself and additional text that you can specify. This could be for a specific event, like Christmas, a sale or the day of the release. As I said 1 GIF is free with each custom order. If you need more, I charge USD10 per GIF. You can show it on Facebook and everywhere else where GIF’s are supported. Click on the images to see the examples in action. We can talk about it when you order your next custom cover, or contact me, if you need those Gifs for already designed covers.
