hi i store an image in sql server file(sdf file) by changing it to an array of bytes,
then when i want to retrive the image and show it in the picture box, i use this method:

public static Image CreateImage(byte[] imageData)
      {
          Image image=null;
          if(imageData !=null)
          {
              using (MemoryStream inStream = new MemoryStream())
              {
                    inStream.Write(imageData, 0, imageData.Length);

                    image = Bitmap.FromStream(inStream);
              }
          }


          return image;
      }

but when i want to save the image retrived from database on the disk with this code:

if (pictueBox1.Image != null)
            {
                pictueBox1.Image.Save(@"pic3.jpg", ImageFormat.Jpeg);
                
               
            }

it gives an error :
An unhandled exception of type 'System.Runtime.InteropServices.ExternalException' occurred in System.Drawing.dll
Additional information: A generic error occurred in GDI+.

also this error doesn't happen when i load image from disk instead of database
