Good translate is your friend.

Pick a language you don't know, and have at it:

"picture site" => "irudi_gune" (basque)

I find that Basque, Portuguese, and Welsh produce very good names.

As someone from Brazil, I wonder what kind of words would sound weird to an English speaker like that. I would have thought that most words would be recognizeable, given that English also has its fair share of Latin words.

Portugese is far enough from Latin that many of the English cognates are not immediately recognizable.

"Sangue bom," for example, is not visually translatable to English.
