How do you get a notification for what picture was viewed? I don't see any Google account setting for that.

That kind of makes me doubt this report, at the very least part of it.

Did she say she got a notification for what picture she viewed? She said "activity logs", which I'm not sure exactly what she means, but it might mean [1] which shows files that have been recently viewed.

Full disclosure, I work at Google but not on anything related to this.

IIRC you get a notification the first time someone views a photo (or maybe for any specific photo?) in a shared album. Maybe the Googler or Googlercontractor was dumb enough to share the album with himself for later perusal?
