New User - Adding snow to a scene ???

[Aswell]

Hi, I am a new user to Gimp because my wife spoke to someone in her art group who said Gimp 2 could be used to add snow to a photo or scanned artwork.


I have looked around Gimp (there's a lot in it!) and cannot find any suggestion to do what she suggests. I have done some tutorials, all very interesting but not addresses what she wants to do.

Is she barking up the wrong tree?
Many thanks, Brian
