Solution 1

Your sending

  comm.Parameters.AddWithValue("name", Path.GetFileName(strFn).ToString());

You should send string fileName;

Try

byte[] ReadFile(string sPath)
       {
           //Initialize byte array with a null value initially.
           byte[] data = null;
           //Use FileInfo object to get file size.
           FileInfo fInfo = new FileInfo(sPath);
           long numBytes = fInfo.Length;
           //Open FileStream to read file
           FileStream fStream = new FileStream(sPath, FileMode.Open, FileAccess.Read);
           //Use BinaryReader to read file stream into byte array.
           BinaryReader br = new BinaryReader(fStream);
           //When you use BinaryReader, you need to supply number of bytes to read from file.
           //In this case we want to read entire file. So supplying total number of bytes.
           data = br.ReadBytes((int)numBytes);
           return data;
       }

at click event of buttonupload try

byte[] imageData = ReadFile(openFileDialog1.FileName);

and pass these imagedata value to sqlcommand parameter as

comm.Parameters.AddWithValue("images",(object)imageData);
