More than 4  years since the first version of securityimages,

SecurityImages for JOOMLA! 1.5 will be out soon

NEW: full translation now possible of static pages about.html, developer.html and troubles.html
NEW: migration to Joomla! 1.5 API, security, database factory, logging, installer -> reduction of code
NEW: unique language files following Joomla! 1.5 convention
NEW: utf8 support

NOT fully MVC for all views in Administration Area
NO added functionalities compare to SecurityImages 4.2.3

Right now I am blocked and can not store any data in the PHP session using
$session = &JFactory::getSession();
$session->set('key', value);

Since all  imageGenerator.php not in a Joomla! include script run

This  is the latest issue, i've seen, and I will find a way to get around it. moreover my site will be also migrated to Joomla! 1.5 in no more than 2 weeks
