What is when a guy says wow to your picture?

As an AI language model, I am not capable of knowing the intentions or thoughts of a person when they say "wow" to a picture. However, in general, when someone says "wow" to a picture of you, it can be a compliment on your looks, outfit, or the overall aesthetic of the photo. It could indicate that they find you attractive or interesting. Nevertheless, it is important to not take every comment on a picture too seriously and always prioritize your safety and well-being online.
