FBML tag to detect user language in a tab

Question

I have a custom tab for a fan page that need to display a JPEG image. I have an image in English and one in French. Is there a way to detect the user locale in FBML to display the right image?

I know how to do this server side using the Facebook fb_sig_locale param but I was planning on just using the Static FBML app which is much simpler than setting up a whole custom application.

You can put constraint by country, for that use this:

<fb:restricted-to location="us">
  <img src="../us_image.gif"/>
<fb:else>
  <img src="../world_image.gif"/>
</fb:else>
</fb:restricted-to>

check here for more constraints possible in fb:restricted-to :
