This was formerly a simple question I was asking, then I changed it to this to save spaceI guess this is the place where I will show off my tutorials and Gimped photos that I did. And I think the name is more than adequate. Since I am somewhat new to Gimp, I have only done some basic stuff, such as this one. I took a random image of mine and added rain and fog to it. I also posted a tutorial on how to do it. So without further-a-do...

The quality would have been better with Photoshop, but I use Gimp as an alternative to PS.
I also took a random SC4 image, and applied the technique:
