While I can't think of a fast way to do it off the top of my head, the Bitmap object (combined with the Graphic object) should contain the methods you need to split up images

If you want to split image for 2 or even cut out few images from one image to others I would go with this approach.

Expand|Select|Wrap|Line Numbers
  1. Bitmap bmpToSplit = ...; // bitmap to be splitted
  2. Bitmap split1 = new Bitmap(w1,h1,bmpToSplit.PixelFormat); 
  3. Bitmap split2 = new Bitmap(w2,h2,bmpToSplit.PixelFormat);
  4. Graphics g1 = Graphics.FromImage(split1 as Image);
  5. g1.DrawImage(bmpToSplit, new Rectangle(0,0,w1,h1), new Rectangle(xSplit1, ySplit1, w1,h1),GraphicsUnit.Pixel);
  6. Graphics g2 = Graphics.FromImage(split2 as Image);
  7. g2.DrawImage(bmpToSplit, new Rectangle(0,0,w2,h2), new Rectangle(xSplit2, ySplit2, w2,h2),GraphicsUnit.Pixel);
THe Point(xSplit#,ySplit#) is coordinate where first image is on original bitmap.
There is a lot things you can do with images with Graphics class.
