== About the Image on the "Sinhalese people" page. == 

 Isn't it possible for you to simply search the images of those people on Google and see if they're copyrighted? There are duplicates of them in random places on the web, so it would be very difficult to find their origins. Or is it alright if you put the image on, until someone reports it in violation of copyright (if it actually IS in violation, that is), in which case you may put the old image back on.  

 I simply found these images through Google Image search. The current image has some people who aren't well-known at all even in Sri Lanka, it's too random and may even appear sexist.
