Media Gallery WKZ (With KZ_Template) is the one to have integrated Media Gallery v1.6.1 and Media Gallery v1.6.8 which is included with glFusion CMS.
To execute Media Gallery WKZ, it is not necessary to install Caching Template Library.
Because the KZ_Template Class which is released by Mystral-kk is included with Media Gallery WKZ. Therefore, the installation is easier.
Because this plugin is so huge, I do not know everything.
But if you're interested, please try.
