I would assume that the photographer took money off the credit card and you should check your bank statements to see that it has been done. I don't see the need for individual receipts - unless it's asked for, I usually don't get one. It also may have been given to your brother.
I don't know why you would assume that the photographer or your brother would provide you a copy of the photo - the photographer may have refused to give another copy, as usually the prices are per copy for photos. They may not have received a digital copy at all so are unable to email it.

And it's only been two weeks. Give it time. I actually don't understand why you'd be peeved in the circumstances that you describe, given the time frame. However, everyone is different.
