I have a bit of a problem. Im using a php file to open photographs in a folder
PHP CODE:
<?php
$location = 'albums';
$album_name = $_GET['album_name'];
$files = glob($location . '/' . $album_name . '/*.{jpg,gif,png}', GLOB_BRACE);
$encoded = json_encode($files);
echo $encoded;
unset($encoded);
All this code is managed from jquery:
JQUERY CODE:

* first gives us the position of the album on the left

The effect is to have a photo stack. I'm using this plugin (I've modified something but not that much):

How can I add a little box with a bit of text under every photo?
I can't understand anything of php so if somebody can help me out would be great.
