Hello all,

what would be the best way to show pictures/thumbnails from an active directory 
in an xwiki site?

So far, we are using groovy to contact an active directoy, extract user info, 
like name, mail, phone etc and return xwiki 2.0 syntax, see code below
Now we would love to extend that contact list with photos stored in the active 
directory. 

Would that be possible? If so, how?

Thanks in advance,
Florian
