90% of the time, a photo of myself with the waymark is sufficient.
Sometimes, though, they specifically want the GPSr in the picture (boo). Sometimes, they specifically don't want me in the picture. Sometimes, they don't require me in the picture, and it would be nice to know in case it's a pain to get a picture of myself with the waymark.
Sometimes, a picture isn't required, and if there are a lot of people around, I may prefer to know that and not take a picture.
Consider this another vote for instructions in PQs.
