Imbo requires a web server (for instance Apache, Nginx or Lighttpd) running PHP >= 5.4 and the Imagick extension for PHP.

You will also need a backend for storing image information, like for instance MongoDB or MySQL. If you want to use MongoDB as a database and/or GridFS for storage, you will need to install the Mongo PECL extension, and if you want to use a RDBMS like MySQL, you will need to install the Doctrine Database Abstraction Layer.
