Determining door swings

I'm slowly replacing my interior hollow-core doors with older wood ones. Vintage doors are almost always shown like the one above - detached and no jamb. I have a tough time determining if it's a left hand/right hand, outside/inside swing. The sellers frequently don't know either since they salvaged them from someplace else. Is there an easy way to tell from a photograph? Are the hinge placements a clue? Thanks!
