This is a simple plugin, does a very simple task. But does it nicely. Activate this plugin, it will disable comments on all Attachment Pages.
Sometimes you see massive spam in your Attachment Pages, it’s tiresome to handle those manually, and comments on Media Attachment does not make sense for most of the website, so this plugin let’t you turn of comments on Attachments entirely.
Just activate the plugin, the comment form on the Media Attachment Pages will be disabled.
