Maybe I just haven't run into the problem you're talking about. Even if I repin from the most current pinner, I still have to click all the way through to get to the original info, tutorial, or pattern. I usually do pin from the original, but I have repinned from others. If it's just a photo with no info, I can't see that it matters. In fact, I think I always pin tutorials rarely if ever do I pin a plain photo.
