We have six WordPress plugins are available for your use. All are free, and all provide a unique add-in for your WordPress sites (in our humble opinion).
Multisite Comment Display
Since the Multisite Media Display and Multisite Post Readers work so well (and are easy to use), we decided that one for comments would be a good idea. And it is! It works like the other ones: just activate it on your main site and then create a page or post with the shortcode. Add parameters to limit the number of comments shown, or only the last x days. Admins will get an edit link to edit comments.
It’s free and fully featured, and available here, although it’s best to get the latest version via the WordPress plugins page – just Add Plugin, and search for it.
Multisite Media Display
We needed a way to look at all the media on all sub-sites of a multisite installation. And we couldn’t find a plugin to do that. And code samples of how to do that were spread out all over the place.
So, we made a plugin. By using a simple shortcode, you can display all the media on all subsites on one page/post. Pictures are displayed with their captions. A second shortcode is used to create picture links that will open the Media Editing page (only SuperAdmins can do this). That’s the reason we built the plugin: we needed a way to see all media on all subsites to ensure terms of use compliance. And you can add a ‘noshow’ caption to pictures you don’t want to display.
Just like our other plugins, it’s free. It’s available here, although it is best to get the latest version via the WordPress plugins page.
