A person did an interesting experiment here (before the nudity in thumbnails ban)  where they posted a thumb of a partially naked female.  The actual picture had nothing to do with the nude female and their view count was astronomicly high.  Not that I think you should post a thumb that is not a part of your full sized pic but an interesting observation anyway.

That being said I try to approach my photography in such a way that if I like the picture that is all that matters.  I aproach my music the exact same way.  (probably why I don't have a recording contaract)  LOL.  If I like my music and it makes ME happy then that is all that really matters.  If just one other person likes it then in my mind I have a masterpiece.  But if no one else likes it then who cares?  I make my art for my sake and just go with that.  I have had only a couple of photos with more than 5 or 10 comments and only one that broke 100 views and I think it was my worst photo posted.  As they say beauty is in the eye of the beholder and there is just no figureing out the human mind.
