Yoast WordPress SEO and Divi theme

I’ve been searching for a while now for an answer to this, and read through many many posts on this topic, but I still can’t find a solution.

I’m using the Divi theme 2.0 from ET, with wordpress SEO by Yoast, 1.5.3.3. I’m building my site and have many images on several pages. The Yoast plugin does not recognize the images when it analyzes the page (I used alt text for all images), and I believe that it has something to do with Yoast not seeing inside the Page Builder area with the Divi theme. In addition, the XML sitemap generated by the plugin reports 0 images on all pages, even though I have not checked the Media option in Exclude post types.

Should I, or can I use a second plugin such as Google xml sitemap in conjunction with the yoast plugin? Should I even be concerned with this issue? All the posts I’ve seen here on this issue seem to get a “topic closed” before a definitive solution is reached. My site is http://www.maraurealestate.com . It’s still a WIP.

Thanks
