Answer 1

Image.RotateFlip will do the job at lot faster and easier:

Bitmap bmp1 = (Bitmap)pictureBox1.Image;
Bitmap bmp2 = new Bitmap(bmp1.Width * 2, bmp1.Height);

using (Graphics G = Graphics.FromImage(bmp2))
{
    G.DrawImage(bmp1, 0, 0);
    bmp1.RotateFlip(RotateFlipType.RotateNoneFlipX);
    G.DrawImage(bmp1, bmp1.Width, 0);
    pictureBox2.Image = bmp2;
}

Instead you could use loops similar to yours and Bitmap.GetPixel and Bitmap.SetPixel but that would be really slow:

TransformedPic.SetPixel(Width - i, j, TransformedPic.GetPixel(i,j));

Going over one half of the width..
