Dramatic images of Superstorm Sandy appeared across Facebook, Twitter and blogs as the storm hit the US East Coast - but many were not what they seemed.

Some came from Hollywood movies, sharks have been photoshopped, and old pictures portrayed as new, but that hasn't stopped many becoming viral sensations.

Here are some of the most dramatic, and fake, pictures, many seen under the Twitter hashtag #FakeSandy.

  • Fake Picture

    This picture, supposedly of Sandy in New York, has been shared over 557,000 times since being posted on Facebook by Jason Otts last night. On his Facebook he wrote: "This is an amazing shot of New York today with the Frankenstorm bearing down. Nature is so powerful, yet so beautiful." But he later posted that he had been duped by a photoshopped picture of a different storm. "Ok… apparently this pic has gone viral from my wall with 99,989 shares. In the last 15 minutes I have had like 200 people add me as a friend because of this pic. So I called the person who texted it to me and she then called her friend who sent it to her and is in New York. He told her that it was fake. So now I have 200 friends who like a photo that is fake on my wall. Funny, but awkward…."

  • Shark Attack?
