All the pictures I have posted have been posted without permission or knowledge of those in the pictures. I will say, I am sure if I asked Lisa or Amy, they would not mind.
In my case, asking them if I can post those pictures is like asking the mountain in the background if I can post the picture with it there... These pictures are about my trip, and my story, and my adventures. These are the things I did, the beautiful scenery I saw, and the people I met. There aren't pictures which are bad or wrong...
Let me put it another way... You have pictures of the woman you love. Do you show your friends without asking if it is OK? SURE YOU DO!! Aren't we all friends here?
Now, some pictures shouldn't be posted, and I think there are obvious differences. I have a picture of Hongping where she just woke up, and is walking to the bathroom She is wearing clothes, but her hair is a mess and it is not a good, flattering picture. I love the picture very much, but it isn't something I would show others. It is important to understand why you are posting, and what others are seeing in the picture. Peter, in your case, you are boasting about your lovely lady, and proudly showing her off to friends. I can't imagine how that is bad. Yes, it is the internet, but the pictures are good pictures, which I believe she would be happy with.
Finally... while I was in China, Hongping came to me while I was online posting on this site. She asked me about it, and I showed her a few things. Mostly the Photos from China forum... she loved it. She knows this site and could come here if she chose to.... and I wouldn't be afraid of her seeing the pictures I've posted. I do understand everyone, every situation, every relationship... is different. But I don't have any problems with people posting pictures of their loved ones, especially when they are very happy and proud of those loved ones. It's nice to show off the loved ones to friends, and maybe boast a little that you have the best woman in the world. I think we all feel that way, and we are all very happy for each other. So, it's all good!!!
