Clicking this will take you to a page where you can upload a photograph and select which profile it will be associated with.
To avoid privacy leakage, we only display the photograph associated with your default profile as the avatar in your posts.
+<a name="language"></a>
+### How can I view Friendica in a certain language?
+
+You can do this by adding the `lang` parameter to the url in your url bar.
+The data in the parameter is a [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) code.
+A question mark is required for the separation between url and parameters.
+
+Example:
+
+ https://social.example.com/profile/example
+
+in German:
+
+ https://social.example.com/profile/example?lang=de.
+
+If the question mark is already in the url you need to do it using a ampersand.
+
+Example:
+
+ https://social.example.com/profile/example?tab=profile
+
+in German:
+
+ https://social.example.com/profile/example?tab=profile&lang=de.
+
+When a certain language is forced, the language remains until session is closed.
