As a user, I want to be able to create blogposts with a photo carousel element. We have started to develop digital articles for our donors, and it would be a useful element as a way of showing our photos. It should be possible to write a bit of intro text and then have the photo carousel beneath. The reader should be able to switch from one image to the next (maybe using arrows in the sides) and each image should have a corresponding caption.
