This plugin will add a widget that displays thumbnails of the most recently posted images from all the blogs in a network. It’s highly optimized to be scalable for large networks, so it should need only about 100 database queries even for a network of thousands of sites. And to keep any performance drain as minimal as possible, the plugin utilizes caching with an adjustable update interval.
<ul>
<li>Note that images are taken only from blogs and posts which don’t have privacy options enabled (compatible with <a href="https://wordpress.org/extend/plugins/more-privacy-options/" rel="ugc">More Privacy Options</a>) and the image must be attached to a post. So essentially, only public images are shown.</li>
</ul>
The widget formatting is completely customizable via a template and/or CSS (if available). The template uses patterns that will plug in values for the following:
<ul>
<li>Image Title</li>
<li>Image Caption</li>
<li>Image Description</li>
<li>Image Thumbnail URL</li>
<li>Full Image URL</li>
<li>Image Publish Date</li>
<li>Parent Post Title</li>
<li>Parent Post URL</li>
<li>Blog URL</li>
</ul>

As my WordPress network grew I found it challenging to track which plugins and themes were used on each site, and the only way to check was to visit each dashboard one at a time. What a hassle!
This plugin adds columns to your Network Admin on the Sites, Themes and Plugins pages to show which of your sites have each plugin and theme activated. Now you can easily determine which plugins and themes are used on your network sites and which can be safely removed.

This is an indispensable tool for MS admins, since WordPress core doesn't include any tools for seeing which MS plugins are in use or by which sites.



Excellent tool

For multisite/network installations only.  Adds columns to your network admin to show which sites are using each plugin and theme.
