    To operate Zenphoto efficiently, you need (our setup script will also tell you about possible problems):

    • A web server with at least 25Mb of free space (plus free space for images and cache files)
    • Apache 2* (it may work without problems on other server systems like nginx, IIS or lighttpd but we have not tested these.)
    • PHP 7, 8, 8.1+ (8+ strongely recommended)
    • It is recommend that you have tat least the following PHP extensions and settings:
      • One of these graphics libaries for image resizing:

      • magic_quotes off (recommended - gone in PHP 8 anyway!)
      • register globals off (required)
      • cURL extension (required)
      • gettext extension (optional, required if you plan to use Zenphoto's translation/multilingual capabilites - note that your server must have the locales for the languages installed you intend to use)
