Usually this is achieved by configuring your webserver to disallow directory browsing on a particular directory. For example, using the apache webserver, you'd use Options -Indexes

The way to do it is to store the images somewhere outside the web container (Tomcat?) like in /opt/data/webapp_name/images/ and write a controller that retrieves the images from that locations. Thus there is no direct access to the images and all kinds of security logic can be added to the controller.
