It's was planned- just like the clue of the photo of his mom's piano.

The goose chase was for finding something he never had.

That makes sense but we would then have to assume that Sean knew someone would get their hands on Walter's wallet to place the photo in there.

But now that I think further, it still doesn't make sense because when Walter visited Sean in the mountains, Sean said he was sitting on the photo, so therefore we would have to assume the photo was there the whole time. To me, it makes the most sense that, like Fish said, the photo Sean took is not from when we see Walter on his break outside the building but from a different day sometime before.
