[Plugin: NextGen Gallery Add-ons] Abandoned plugin: Please delete.

This so-called plugin creates only a single function (a shortcode handler) which is not usable, as it is never linked to a shortcode; and it is dubious whether it would work even if it were. In other words, the plugin does nothing at all.

There is no author plugin homepage (not even a DNS entry for the site) and the author has apparently abandoned it.

Please delete this plugin from the WP database.
