Logo on Images

Question

User1906504752 posted

I want to put my logo on uploaded images.  

I used this code.. But it enlarges the Logo image and the logo is not getting a good qulity.

 

  string imgPathTemp = Server.MapPath(string.Concat("~/upload/temp/", Images[j].ImageName));
                        System.Drawing.Image imgTemp = System.Drawing.Image.FromFile(imgPathTemp);
                        Bitmap bitmapSmall = CreateThumbnail(imgTemp, 80, 60);
                        bitmapSmall.Save(Server.MapPath(string.Concat("~/upload/final/small/", Images[j].ImageName)), System.Drawing.Imaging.ImageFormat.Jpeg);
                        bitmapSmall.Dispose();

                        Graphics graphTemp = Graphics.FromImage(imgTemp);
                        System.Drawing.Image imgOverlay = System.Drawing.Image.FromFile(Server.MapPath("~/App_Themes/" + Page.Theme + "/images/videoOverlay.png"));
                        graphTemp.DrawImage(imgOverlay, imgTemp.Width - imgOverlay.Width - 20, imgTemp.Height - imgOverlay.Height);
                        imgTemp.Save(Server.MapPath(string.Concat("~/upload/final/large/", Images[j].ImageName)), System.Drawing.Imaging.ImageFormat.Jpeg);

                        graphTemp.Dispose();
                        imgTemp.Dispose();
                        imgOverlay.Dispose();
