I’ve uploaded a new beta version of AWSOM Pixgallery version 4.6.0 that can be downloaded here. This version of the plugin adds in the new custom language capability. By editing the pixgallery_lang.php file you can change the display of all of the nav elements of the plugin. Additionally you can place a copy of this file into a new folder called custom_language so that updates to the plugin do not erase any of your changes.
I also made a small bug fix to correct an issue where the next/previous archive nav elements did not appear in the proper place, and they now follow the option for “extra nav bars” and appear at the bottom of the thumbnail gallery if this option is turned on in Pixgallery settings.
