Up until this point, Easy Image Gallery has been packaged with fancyBox 2. Unfortunately I completely overlooked the licensing of fancyBox 2, which is licensed under the Creative Commons license. Non-GPL licensed software cannot be hosted on the WordPress repository and because of this, I’ve replaced fancyBox 2 with fancyBox 1, which is GPL licensed.
If you’d like to add fancyBox 2 back into the plugin, simply download the free Easy Image Gallery Extend plugin. After activation, you’ll find fancyBox 2 (as well as Colorbox) under the plugin’s settings.
