Copyright pictures?

[lv4dogs]

I don't think you have to purchase a copyright. I have a website for my pics with a photography name (TigerLily Photography) but I just put BP or Briana P. on my pics. I'm sure Kay would know more about this though, since she's been (c) her's longer than me.

So in order for the (c) to show up on the pic, do you have to edit the pic, or do only limited sites offer this option?
