Gay-vague advertising

I know we only talked about gay-vague advertising briefly in class, but I'm so interested in it. It's amazing to me how two people can look at a picture/image/ad and see two completely different concepts based on their sexual orientation. When I look at an ad with two people of the same sex, I almost always see a platonic relationship. I really think that when a gay person looks at the same ad and sees more than a platonic friendship, he or she is right. I think they have an insight that straight people don't.
