Instead of trying to collect these images into a facebook post I put them in a separate web page. This also avoids posted images in facebook that slow the scrolling through posts.
I find these images very interesting; perhaps others will also. You just have to click once to get there. The page with this link has links to the descriptions and to just the images. The images are zoomable to reveal more than I mention if someone is curious.
