I LOVE the picture. However, in the past LinkedIn has removed non-professional photos, including pictures of dogs, babies, etc. I don't know if they still do this and I'm not agreeing or disagreeing with this policy, I just wanted to make you aware of it.

Additionally, if your photo is not an image of yourself or does not contain an actual photograph, it is considered inappropriate." This is from October 2008, so I am not sure if it's still accurate.

As I recall, even here someone posted to ask me what they were.
