This post try to explain how to resize an Image, that is passed as parameter.

Code:

        private static Image resizeImage(Image imgToResize, Size size)
        {
           int sourceWidth = imgToResize.Width;
           int sourceHeight = imgToResize.Height;

           float nPercent = 0;
           float nPercentW = 0;
           float nPercentH = 0;

           nPercentW = ((float)size.Width / (float)sourceWidth);
           nPercentH = ((float)size.Height / (float)sourceHeight);

           if (nPercentH < nPercentW)
              nPercent = nPercentH;
           else
              nPercent = nPercentW;

           int destWidth = (int)(sourceWidth * nPercent);
           int destHeight = (int)(sourceHeight * nPercent);

           Bitmap b = new Bitmap(destWidth, destHeight);
           Graphics g = Graphics.FromImage((Image)b);
           g.InterpolationMode = InterpolationMode.HighQualityBicubic;

           g.DrawImage(imgToResize, 0, 0, destWidth, destHeight);
           g.Dispose();

           return (Image)b;
        }
