posts are being generated for random images

Not sure what your question is… Are you talking about the search engines or your WordPress site?

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.

Can you send a link or screenshot of what you are referring to?

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 https://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.

here are a couple more.

When I open these images in the WordPress admin/media library and ‘view attachment page’ it shows the pages I linked here.

Ah, attachment pages that is a default WordPress function… https://www.google.com/search?q=attachment+pages

Usually we are not permitted to offer support for commercial themes as your theme has a support page dedicated to it @ Themeforest.

But there are a number of ways to disable the attachment page in the link above. Or you can google “Disable Attachment page”
