Just to clarify, as I said above, I did NOT ever enter the photo into any Photobucket contest (or any other contest for that matter). The only place that I had ever posted the photo prior to the CBS usage was to a post on one of my own websites (http://www.thedorsal...-hours-to-days/). The only other time that I have posted the photo since is in these comparison photos.
Scroll around and you will find it. I hope you didn't enter it as I called it out. Ooops?
I've never entered any Photobucket contests, but I didn't see my photo in there (although, I didn't look at every single picture). The white shark photo that appears in the top-15 of that contest is the same one that was added to the Creative Commons by somebody who didn't actually take it. However, that photo is not mine.
If your sure it's your image I would contact CBS and send them a bill. You need to be paid for your work even if you don't conceder yourself a pro. The problem is a lot of these images look the same and if the guy in the cage next to you submits his image it's sometimes even harder to see a difference. I don't doubt that it's yours I would just double check.
I did several comparisons with the photo and and screen-caps from the CBS vid. As you can see in the above comparison, there is a mackerel scad tail in the exact same spot on the left side of the photo, the shark is in the same position, lighting is identical. It seems the image might have been additionally processed, but I'm fairly certain it's the same image. I've even done overlay in PS with the original image on a layer and the screencap below and modified the opacity for comparison's sake. There is even a particle of "scatter" above the tail of the mackerel scad that shows up in the exact same spot in both images when viewed at full-size.
