We have an assortment of designs that allow you to put captions on each photo, so that you can have different text for each slide. These designs are under the "Slideshows" category in the Design Catalog. You will continue to see new slideshow designs on a regular basis as we add new content. This blog post walks you through all of the types of designs available in Ripl.
The Slideshow designs can be located by creating a new post from scratch, selecting "More Designs" on the "Customize" page and navigating to "Slideshows".
In the desktop version of the Ripl app, once you add more than 1 photo to a slideshow design, a slide counter and arrows will appear in the bottom of the post preview, which will allow you to switch between slides and add additional wordings by clicking on the "Text" button and selecting the "Text Caption" field.
