I suspect that pictures are rectangular since the film is (well, was anyway) that way. Of course cutting apart pictures when they process them is easier with straight cuts too, not to mention storing them away.
But if you had round film - you can take round pictures.
But how does a round lense take a rectangular picture? I mean, the lenses on digital cameras are round, and there's no film in them... So why do the pictures still come out rectangular?
That is a very good question! Since I also didn't know the answer, I looked it up at ask.com. Here is what I found:
"I don't know about digital cameras but in a camera using film the portion of the camera that holds the film against the back inside wall,directly behind the shutter is square. Open the shutter and the area is flooded with light. The only portion of the film exposed to the light is that area of the film inside the square."
I think what this all means, is if the lens were square or rectangular, it wouldn't allow for focusing or zooming in. Being round, allows for that.
What a neat question. Maybe it works that way in the digitals as well Chicago. Since the part letting the light in is square then that's how it gets saved to the disc?

This website has a bunch of pictures to show what he's talking about, but perhaps you can understand it, just by reading it.
