Definately talk to her about your photos. I'm sure she values you as a customer and would want to hear your concerns.
As a longarmer, I always ask if it is okay to put a photo of my client's quilts on my website. The work order form they sign includes a space for them to initial with their approval. When I refer to the owners of quilts on my blog I typically include only their first name for privacy reasons. Your post, however, has given me plenty of food for thought and I thank you for posting it.
If you have found a longarmer you trust and who "clicks" with you, don't jump ship. It is so important to find a quilter you feel comfortable with. Just express yourself and I'm sure she will be happy to work this issue out with you.
