haha i think this is halerious, so u knw that there is a few softwares that can do it but u dont knw the names. whats teh deal
Try doing a Google search or three. It only took a few minutes to turn up this review
of Paint Shop Pro 8 which boasts "Lens Distortion - Create fisheye, barrel or pincushion effects
". If you spend more time than I have available I'm sure you can turn up a wide range of software which includes similar functionality at all prices.
Bear in mind that any software which simulates the fisheye effect is likely to be limited because the source photograph will usually have a smaller field of view than a genuine fisheye image.
As Henning91 says, Google is your friend.
