How to show flags with qtranslate?

I am a newbie on wp and want to build a multilingual blog in japanese, swedish and english. I successfullly installed qtranslate and I was able to use activate the plug and it seems to work as intended.

One minor flaw, though (most likely due to my own shortcomings in understanding how to edit the appearance in wp), language options are only shown with text….there are no flags..

I would like to use flags instead of text….looking at other wp-users that use qtranslate, I see that they use only flags….

I read the FAQ section at the home page of qtranslate please see below link….

There is a code presented in how to make the flags appear, but I do not understand where I should edit/or paste this code.

Is there any one that knows how to do this? Any support on this item is highly appreciated.

Thank you very much in advance for your support.

Best Regards,
