Answer 1

You can save the image in a folder and save the address of the image in the folder in the database or convert the image to an array of bytes and save it in the database and convert the bytes to the array when retrieving.

save image to folder

public void SaveImageToFile()
{
            OpenFileDialog opFile = new OpenFileDialog();
            opFile.Title = "Select a Image";
            opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";

            string appPath = Path.GetDirectoryName(Application.ExecutablePath) + @"\ProImages\";
            if (Directory.Exists(appPath) == false)                                             
            {                                                                                   
                Directory.CreateDirectory(appPath);                                             
            }                                                                                   

            if (opFile.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    string iName = opFile.SafeFileName;  
                    string filepath = opFile.FileName;   
                    File.Copy(filepath, appPath + iName);
                    picProduct.Image = new Bitmap(opFile.OpenFile());
                }
                catch (Exception exp)
                {
                    MessageBox.Show("Unable to open file " + exp.Message);
                }
            }
            else
            {
                opFile.Dispose();File.ReadAllBytes()
            }
}

and for convert image bytes to picturebox

public static Bitmap ByteToImage(byte[] blob)
{
    MemoryStream mStream = new MemoryStream();
    byte[] pData = blob;
    mStream.Write(pData, 0, Convert.ToInt32(pData.Length));
    Bitmap bm = new Bitmap(mStream, false);
    mStream.Dispose();
    return bm;
}

and convert image to bytes

public byte[] ImageToByteArray(string fileName)
{
   return File.ReadAllBytes(fileName);
}
