Gallery 2 Pre-Installer Instructions:

1. Open preinstall.php in a text editor and set the password by editing
   the $passPhrase = ""; line e.g. to
   $passPhrase = "my secret passphrase";

2. Upload preinstall.php to your website to the folder where the gallery2
   folder should be created, e.g. to / if you want that your Gallery 2
   will be installed at http://example.com/gallery2/.
   
   Note: You can later rename the gallery2 folder if you want to, but
         the initial name of the folder will be gallery2.
         
   Note: http://example.com is just an example. 
         The address will be different in your case.
   
3. Browse to http://example.com/preinstall.php to start the pre-installer.

4. Enter there your password (e.g. "my secret passphrase" without the 
   quotes) and follow the instructions.

5. Once your Gallery 2 is extracted on the server, install it by following 
   the link to the installation wizard.

6. Remove the preinstall.php script from your server since it is a 
   potential security risk if it is left on the server.

Note: This pre-installer just transfers and extracts Gallery 2 to your 
      webserver. It is a convenient and fast alternative to uploading
      all the extracted files yourself with an FTP program.
      If you have SSH / shell access, we recommend extracting the archive
      yourself of course.
