{
using (Graphics FinalImage = Graphics.FromImage(FinalBitmap))
{
// Draw the first image staring at point (0,0) with actual width and height of the image, in final image
FinalImage.DrawImage(img1, new Rectangle(0, 0, img1.Width, img1.Height));
// and Draw the second image staring at point where first image ends in the final image and save changes
FinalImage.DrawImage(img2, 0, img1.Height);
FinalImage.DrawImage(img3, 0,img2.Height);
