MediaGallery fonction Random Full Image

Create static page with this code:

$rutaImagen = phpblock_mg_randommediaFull();
$pathalbum = phpblock_mg_randFull();

echo "<center><img src='$rutaImagen'></img></center>";
echo "<center><a href='$pathalbum'><b>Votar</b></a></center>";

And we need to add this code to lib-custom.php

* albums.  It uses the full (orginally uploaded image) for the display.
 *
 * This function can be called from a static page or a block
 *
 * Staticpage Instructions:
 *
 *   To use this function in a static page, the static page must allow PHP
 *   to execute.
 *
 *   Place the following code in the static page:
 *
 *   echo phpblock_mg_randommediaFull();
 *
 * Block Instructions:
 *
 *   Create a Geeklog block, type PHP Block and enter phpblock_mg_randommediaFull
 *   as the Block Function.
 *
