When I open these images in the WordPress admin/media library and ‘view attachment page’ it shows the pages I linked here.
I included a link to a sample page in my original post. This particular image is used by a 3rd party system on our site and not on any actual page, but I have seen it happen with images that are used in pages. The url is always http://www.domain/image-name and uses the blog template with the image as the only content. I was hoping someone out there would have seen this before.
It looks like WordPress is generating the posts. I want to know where these posts are coming from and how to make them go away.
