How to get Revolution Slider Images in Sitemap

I use the Revolution Slider as apart of the Miami theme. I also use Yoast SEO to create my xml sitemaps. However, the images in the revolution slider are not listed in the sitemap.
Has anyone successfully added Revolution Slider image to their sitemaps? If so, then how.

Thanks in advance.

I’m having the same issue and would be very interested in a solution.

Does anybody here can help?

Ive put a support request into Revolution slider as I am having the same issue with “any image sitemap plugins” never mind just Yoast. Ive been told over 2 weeks ago this will be implemented in future updates, Ive been away on holiday and dont know if this feature has been implemented in recently released as an update
