加图片水印：
System.Drawing.Image image
image=System.Drawing.Image.FromFile(path);
System.Drawing.Image copyImage = System.Drawing.Image.FromFile( Server.MapPath("upload\\126.JPG") );
Graphics g = Graphics.FromImage(image);
g.DrawImage(copyImage, new Rectangle(0,0, copyImage.Width, copyImage.Height), 0, 0, copyImage.Width, copyImage.Height, GraphicsUnit.Pixel);
g.Dispose();
image.Save(Server.MapPath(newPath)+System.DateTime.Now.ToString("yyyyMMddHmmss")+exName);
image.Dispose();
加文字水印：
image=System.Drawing.Image.FromFile(path);
Graphics g= Graphics.FromImage(image);
newimage=image.GetThumbnailImage(smallImage_Width,smallImage_Height,callb,new System.IntPtr());
Font f=new Font(watermark_text_FontName,watermark_text_FontSize,FontStyle.Bold);
SolidBrush b=new SolidBrush(Color.Red);
g.DrawString(watermark_text,f,b,10,10);
g.Dispose();
image.Save(httpcontent.Server.MapPath(newPath)+System.DateTime.Now.ToString("yyyyMMddHmmss")+exName );
