NGUI Localization Format

[animotion.tm]

We are using NGUI version 3.5.8 unitypackage.
In example #10 (localization) we are given an option in the form of a "drop-down menu" in order to choose our desired language.
The question is how to replace this "drop-down menu" format with a series of icons each representing a single language, so that the user can simply browse the list of languages and click on the desired icon?

The user interface elements you use is relatively irrelevant. You can use buttons, drop-downs, sliders or anything else to switch the language.
Simply calling 

1. Localization.language = "yourlanguage";

will switch the language.
So you could just create a button and call a function that calls the above line on OnClick.
