After seeing these pictures, I would say you have a really high chance of getting that parking ticket dropped. I guess what it really comes down to is the judge. Hope you get a good one. Anyways, yeah its definitly worth fighting in my opinion
PS. you should definitly take new better pictures. You don't want the judge to screw you over because of the blurryness of the pictures.
