Question

Does anyone know of a way to display a thumbnail image from a byte array, or even better, a library that does this. Thanks

Answer 1

public ActionResult Thumbnail() {
            byte[] myByte = System.IO.File.ReadAllBytes(location);
            Image i;
            using (MemoryStream ms = new MemoryStream()) {
                ms.Write(myByte , 0 , myByte.Length);
                i = Image.FromStream(ms);
            }
            return File(imageToByteArray(i.GetThumbnailImage(100 , 100 , () => false , IntPtr.Zero)) , "image/jpeg");
        }

        public byte[] imageToByteArray ( System.Drawing.Image imageIn ) {
            MemoryStream ms = new MemoryStream();
            imageIn.Save(ms , System.Drawing.Imaging.ImageFormat.Gif);
            return ms.ToArray();
        }

This is what i used. Instead of doing this each time i want a thumbnail, i created a new column in my table that was a varbinary and called that column each time i wanted a thumbnail.
