Hi Ann -- welcome to ATP and to the Iris Forum!!
You can post your pictures here, and we will try to help you -- but you need to know up front that identifying Irises from pictures is a very difficult task. There are so many that look alike, and only subtle differences would confirm or deny an identification. Of course, it's those subtle differences that generally don't show up in a picture. What we may be able to do is guide you to possibilities where you could do further research. Ultimately, the only sure way to identify an Iris is to grow the suspected variety right next to your mystery Iris -- and bloom time will tell you if you are right or wrong. But hopefully we'll be able to help you narrow down the possibilities.
The Database is a wondrous source of information!!
