In WordPress, attachments default to having their own pages. Sometimes, 
this is not desirable, as in search engine results. Use this small plugin to 
redirect your attachment pages to the post parent using a 301 redirect 
(post parents are also searched for by post name). If an attachment parent post 
cannot be found, it redirects to your blog home page with a 302 redirect.

Attachment Page Redirect X

Redirect attachment pages to their parent page (301), when possible, otherwise to the blog home page (302).

What is a 301 Redirect? 
A redirect is a simple way to re-route traffic coming to a Requested URL to different Destination URL.
A 301 redirect indicates that the page requested has been permanently moved to the Destination URL, and helps pass on the Requested URLs traffic in a search engine friendly manner. Creating a 301 redirect tells search engines that the Requested URL has moved permanently, and that the content can now be found on the Destination URL. An important feature is that search engines will pass along any clout the Requested URL used to have to the Destination URL.

When Should I use 301 Redirects? 
* Replacing an old site design with a new site design 
* Overhauling or re-organizing your existing WordPress content 
* You have content that expires (or is otherwise no longer available) and you wish to redirect users elsewhere
Is the 404 error log GDPR friendly? 
The 404 error log does not collect user IPs. It collects the following data: timestamp of the event, the (404) URL that was opened, and the user-agent string.
