I'm guessing the whole Sanji's bad portrait the first time... WAS ON PURPOSE!

While yes, we have an official explanation, why couldn't they just find him and take a picture? Easy. The Vinsmokes saw it, and knew who they were talking about, and made it stay. When Sanji's second bounty came in, it was impossible for them to ignore it, so they just said 'Keep Him alive'. I bet the whole wedding thing is actually a punishment for his pirate ways.
