 :Hi! Regarding photo that I've uploaded: I'm not familiar with GDFL and that other stuff, but picture is from Serbian Wikipedia, so i guess that it's not copyrighted. Djordjes posted it on Serbian wiki, and here is his User page on Serbian wiki, where you can contact him in English (or tell me what to ask him).  
 By the way, Jovan Ducic died in 1943, 62 years ago, so copyright of this photo (if any) should have expired long ago   "
