Coppermine Photo Gallery Tunnel for Joomla!, phpBB3 or Invision Community 4
version: 1.3.5

The four files in this package are plugins for CPG, Joomla!, phpBB(3.1+) and Invision Community 4.
The phpBB3 and Invision Community tunnels can function with installations that have been bridged with CPG.

For CPG:
--------
Install the plugin, cpg1.6.x_plugin_tunnel2cpg_v1.3.4.zip
Configure its 'secret phrase', encryption method, usergroup settings, whether to sync passwords and optional theme name.
The tunnel encryption phrase/method must be set the same for each tunnel component (CPG and Joomla/phpBB3/invision4).

For Joomla!:
------------
Install the plugin, plg_system_cpgtunnel_v1.3.2.zip
Enable the plugin and configure its 'secret phrase' (phrase same as CPG), encryption method and usergroup settings.
Establish any links in Joomla! that will point to CPG as: <CPG URL>/index.php?file=tunnel2cpg/joomla
Use the same link when setting up access to CPG using a Joomla! menu item 'wrapper'

For phpBB3:
------------
Unzip the extension, ron4mac_tunneltocpg_v1.2.1.zip, into the <phpbb>/ext folder.
Enable the extension and configure its 'secret phrase' (phrase same as CPG), encryption method and usergroup settings.
Establish any links in phpBB3 that will point to CPG as: <CPG URL>/index.php?file=tunnel2cpg/phpbb3

For Invision Community 4:
------------
From the Admin Plugins area, install the plugin file invision4CPGtunnel_v1.xml
Enable the plugin and configure its 'secret phrase' (phrase same as CPG), encryption method and usergroup settings.
Establish any links in IC4 that will point to CPG as: <CPG URL>/index.php?file=tunnel2cpg/invision4


NOTES:
------
Mcrypt encryption methods can not be used with PHP version 7.2 and later. You must use openSSL.

Joomla!, phpBB3 and IC4 users will have to logout and back in before a tunnel will be established.
Subsequently, when users logout from Joomla!, phpBB3 or IC4, they will also be logged out of CPG.

Once users have accessed the CPG instance via Joomla!, phpBB3 or IC4, they will also be able to go directly to the
CPG instance (<CPG URL>) and login with their same Joomla!, phpBB3 or IC4 username and password.

A sample CPG theme is provided that is designed for use when accessing CPG via a Joomla! menu item wrapper.
