In <b>index_image_mysql.php</b>, variable <i>$_SERVER['REQUEST_URI']</i> is taken to fetch image from DB. The problem is that this variable also contains the query string (ie <i>?nocache=12345783</i>) and fails when adding parameters to avoid browser caching an image.

It would be better to take <b>$_SERVER['SCRIPT_NAME']</b> as a reference :

<b>Actual index_image_mysql.php (line 33)</b> :

$filename = ltrim( $_SERVER['REQUEST_URI'], "/");

Should be :

$filename = ltrim( $_SERVER['SCRIPT_NAME'], "/");

Note : Also affects <i>index_image_mysqli.php</i> and <i>index_image_dfsmysql.php</i> (4.2)

Steps to reproduce

While using clustering, try to display an image with a query string.
Example : http://myhost/var/myvar/storage/images/media/images/test-image/3122-2-fre-FR/test-image_large.jpg?myquerystring

Displays a 404 error, while the image really exists
