When I insert an image into a post, I have the option of attaching a URL to the image--either the image URL or the POST URL. When I select POST URL, clicking the image does not take the visitor to the POST as expected but rather opens up the image as an ATTACHMENT page. Sure seems like a defect. It's caused by the rel="attachment wp-att-240" in the anchor tag. Impossible to find solutions when searching this forum, searching for BAD LINKS returns pages of 5 year old posts... Badly need advanced search capabilities on this website... Thanks for all who respond.
