Image in navigation label?

I’d like to place a little flag image in a navigation label. Where can I find the code and do this manually? Or is there an easier way?

Just an observation: it is conceptually incorrect to associate a language to a flag, because languages are transnational while country flags are not (by definition). I’d suggest to use 2-letters codes, instead.

True, but a 2-letter code assumes some literacy in a foreign language with a different alphabet (in my case with an Arabic-English site). I’d much prefer flags if there’s a way to do it.

Though I’m still open minded to your Multilanguage plugin, I’m just not sure how to fix the error message I’m getting.
