Adding phpmyadmin to my default site

[Dieter Zinke]

The source code for the main login page gives this:

<div class="container">
<a href="http://www.phpmyadmin.net" target="_blank" class="logo"><img src="./themes/original/img/logo_right.png" id="imLogo" name="imLogo" alt="phpMyAdmin" border="0" /></a>
<h1>Welcome to <bdo dir="ltr" xml:lang="en">phpMyAdmin </bdo></h1>

Trying a http://localhost/phpmyadminthemes/original/img/logo_right.png via browser results in a 404 Not Found nginx.
