Hey guys, I need opinions from those who take  photography serious. 
  
Below are two pics taken by my brother after I loaned him my Kodak didgital camera. After he returned it and we downloaded these pics, I brought up to him what I thought was all over the one pic with spots. This lead to him flying off the handle and a scuffle ensued.  I'll leave that part of the story as is... 
  
The camera looks fine now, and shows no signs of anything that could cause those spots. I have taken pics since, with no spots showing, or has this ever happened while I've used it.  I need you to tell me, what would you assume to be the cause of those spots ? 
  
thanks
