Scan your WordPress installation for all missing attachment files, download them from another WordPress installation and resize them with your defined image sizes.
Know that the plugin will not create new media on your installation database, it’ll just use the existings entries of medias in your database to retrieve the physical files on another WordPress installation.
E.g.: http://serverA.com have an entry for the mediaX in his database. The path for the physical file is supposed to be http://serverA.com/wp-content/uploads/2013/06/mediaX.jpg but it’s not here. If you know that this same media exists on http://serverB.com + the physical file, you can use this plugin on http://serverA.com, specifying http://serverB.com in the Server URL field and the plugin will search the file here: http://serverB.com/wp-content/uploads/2013/06/mediaX.jpg. If it find it, it will be downloaded here: http://serverA.com/wp-content/uploads/2013/06/mediaX.jpg.
<h4>Do you need this?</h4>
This plugin is useful if you have multiple instances of a same project installed on multiple servers.
For example, a team of developers, each of them having a copy of the “master” installation located at the production server. Periodically, the database of the “master” installation is given to the developers who update their code through a <a href="https://en.wikipedia.org/wiki/Revision_control" rel="nofollow ugc">VCS</a> (like SVN, GIT, Mercurial). There is chance that the uploads folder is not versionned, which is good, so the plugin is useful here to download the medias from the “master” installation.
<h4>How tu use it?</h4>
In the admin, go to Tools/Import and choose the Attachment files importer. From here, enter the URL of the WordPress installation that contain the physical files of medias and click Import.
Existing files will not be overriden.
<h4>Debug</h4>
The plugin is in an early stage and bugs may occurs. If you want to show a detailled report of the importation process, add this line to your wp-config.php file:
<pre><code>define('ATTACHMENT_FILES_IMPORT_DEBUG', true);
</code></pre>

WP Users Media works right away when you activate the plugin. No more settings needed. If you need the options switched on for the Admin also you can do it in the Options Page located in the Settings area.
What the plugin does is to disable the ability for users to access other members files and attachments through the Media Button and Featured Image sections. This is really good because maybe you have Authors, Contributors and Subscribers that write posts etc. and you do not want them to be able to use other members media files to their own content.
To test it out create <code>3 users</code>, <code>1 Admin</code> and <code>2 Author's</code> for an example. As Admin you are able to see all media files from all the users on the site.
<ol>
<li>Upload some photos or other media files as Admin. Log out</li>
<li>Login as <code>Author 1</code> and click on the Add Media button for an post or a page. Now you do not see any media files at all. If the plugin was inactivated you would be able to see the photos that the Admin uploaded. Now, upload some photos as <code>Author 1</code>. Log out.</li>
<li>Repeat step 2 for <code>Author 2</code>. As you can see <code>Author 2</code> cannot see the files uploaded from the Admin and from the <code>Author 1</code>.</li>
</ol>
This is very effective solution to keep the media files more private.
