The images you have noted in common use are images that are supplied with Microsoft Windows.

Many players have no other images on their hard drives when they go to create an image, and have no experience editing or creating their own image. Often such users choose one of those stock images that come with Windows. These images include (but are not limited to):

A winter snow scene, blue and white
A purple flower close-up
A deep red-orange sunset

When you see one of these images used by more than one player, please rest assured that the players are not likely working as a team but merely chose the same image because it was one of very few on their computer.
