I think it's a neat photo, and I appreciate the spirit of your post, but I recommend you to modify or delete it, unless you got his consent to post.

Not that anyone would, but I would be creeped out if I learned that people were posting pictures of my office without my knowledge.

It's public knowledge that he's a prof at stanford and publicly available directories can lead you to his office. Not to mention that he's famous enough that this is almost certainly not the first time someone shares a photo like this.

If it was a photo of his home I'd understand but this is essentially public knowledge.
