Getting started and what to check

Make sure that the NextGEN gallery plugin is activated, by going to the Plugins page.

Make sure that the WPML Multilingual CMS, WPML String Translation, WPML Translation Management, and WPML Media Translation plugins are activated.

WPML offers two translation editors you can use for translating your site’s content:

Besides translating your site content yourself, you can also:

  1. Create a page in your original language and add a NextGEN Gallery to your page. In our case, the original language is English. Once your Gallery is created, make sure to display it on the page and to publish it.
  1. Click on the plus button in the Language box.

Your Gallery is now displayed on the French version of your page. However, the Gallery is still in English; it still needs to be translated. This will include translating the description, caption, and the rest of the strings.
