Teak supports localizing both images and text for any Facebook supported language.
For example, here is our editing interface with English (US) text.
At the top of each object page you will see this bar across the top. In the dropdown you can select the language you want to edit.
Once you set which language you want to use, you can input the new strings and image for your object, and click Save.
Here is the same object with Spanish text.
Once you hit save, it's ready to go! People using Facebook in the language you just added will see your content in that language.
When a Facebook user has their language set to English, they will see this object in English. If they have their Facebook language set to Spanish, they will see this object in Spanish, like this:
If a translation is not provided Facebook will use the English (US) text and image.
If you have localizations in a spreadsheet or other format, please contact us and we will help you import your data.
