The whole beauty of this is that It's in the eye of the Beholder (That'll be YOU).
The only reason you think these pictures are looking right at or through you(whatever), is because (unconsciously) you want them to, by paying extra special attention to them(especially to their eyes).
The same phenomenon can be applied to most other people, but it only starts to bug you(or anyone else) is when you more or less, let your imagination take the best of you.
How to fix it, pay no attention to them. Don't think that they ARE looking at you, etc........
