Hi. The images can be indexed by Google, but it also depends on how you load the images. If you enable lazy loading, which means that images will not be added in the page until the slide is navigated to, in order to speed up page loading and reduce bandwidth, the lazy loaded images which are not visible from the start might not be indexed. To be clear, the initially visible images will be indexed even if they are lazy loaded, but other images which require navigating through the slides in order to load, might not be indexed. This is the case only if you enable lazy loading; if you don’t, then all images should be visible for indexing.
Best,
David
