Just like regular posts and pages, attachments have their own <a href="https://codex.wordpress.org/Using_Image_and_File_Attachments#Inserting_Images" rel="nofollow ugc">pages</a> where guests can leave comments (and can also accept trackbacks/pingbacks). Unlike regular posts and pages, attachment pages don’t offer any UI controls that let you choose (on an individual basis) which attachment pages should allow comments and pings.
This plugin corrects this issue by giving you the ability to turn comments and pings on or off for individual attachment pages within your media library.
The global setting to allow comments or pings by default already applies to attachment pages.

Ever had someone comment on a post on your site that is really old? With the Advanced Comment Control plugin you can automatically disable commenting on old posts, or only allow certain roles to comment on certain post types. This is one of the easiest ways to handle spam and trolls.
What can you do with the Advanced Comment Control plugin for WordPress?
<ul>
<li>Disable comments on select post types older than a certain date.</li>
<li>Disable comments on select post types with more than a set number of comments.</li>
<li>Disable pings/trackbacks on select post types older than a certain date.</li>
<li>Disable pings/trackbacks on select post types with more than a set number of comments.</li>
<li>Set roles that can always comment on select post types.</li>
<li>Set roles that can never comment on select post types.</li>
<li>Set rules for logged in or logged out users.</li>
</ul>
