Swrve does not host images or other assets. If you want to resource A/B test images or other assets in your app, you can create references to your images in Swrve and then A/B test the references. For example, for a web-based app, image URLs (with the images stored on CDNs) could be changed as part of an A/B test.
However, we do manage the delivery of images used for in-app messaging A/B tests. For more information, see A/B testing in-app messages.
