Say your client wants to add a custom upload button somewhere in the admin page but it is not possible with WordPress built-in hooks.
In that case, use this plugin to embed an uploader link. Example rules will be created when you first activate the plugin and you can modify those to suite your needs.
<h4>Options</h4>
<ul>
<li>decide whether a button should be replaced with an existing element or inserted.</li>
<li>redirect the page after the user upload a file.</li>
<li>disable the <code>Library</code> tab in the uploader window.</li>
<li>restrict file types to be uploaded.</li>
</ul>

Uploader Anywhere

Inserts uploader modal window links anywhere in the admin area.

This plugin simply places a small, bordered note with an optional link at the top of the admin pages 
inside the WordPress dashboard. Nothing fancy, just a simple way to draw the attention of everyone 
who might be visiting the admin pages to something important, where the README files for the site are, 
for instance.
Obviously, this plugin will primarily be useful to sites with multiple administrators.

Admin Header Note

Places a small note with an optional link at the top of the admin pages.
