Imager resized image not shown (404)
Solution: 

I have this line inside my config.
define('BASEPATH', realpath(dirname(__FILE__) . '/../') . '/');

And inside the imager config file imager.php I have: 
'.dev' =&gt; array('imagerSystemPath' =&gt; str_replace('craft/','images/', BASEPATH),

So, make sure the paths are all set according to your environment / directory structure.
