Hello ,

you just take one picturebox control from the toolbox . now set the picturebox image by this way.

private void btnBrowser_Click(object sender, EventArgs e)
     {
         openFileDialog1.Title = "Choose Image";
         openFileDialog1.Filter = "Images (*.JPEG;*.BMP;*.JPG;*.GIF;*.PNG;*.)|*.JPEG;*.BMP;*.JPG;*.GIF;*.PNG";
         if (openFileDialog1.ShowDialog() == DialogResult.OK)
         {
             Image img = new Bitmap(openFileDialog1.FileName);
             pictureBoxCompanyLogo.Image = img;// resizeImage(img);
         }
     }

and before save this image into database , convert this picturebox image into byte[] format .

public static  byte[] ImageToByteArray(Image img,PictureBox pictureBoxCompanyLogo)
        {
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            if (pictureBoxCompanyLogo.Image != null)
            {
                img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            }
            return ms.ToArray();
        }

and call this method

byte[] byteImg=ImageToByteArray(pictureBoxCompanyLogo.Image, pictureBoxCompanyLogo);

Now save this byte[] image in your database (in the Image column of sqlserver)

while retrieving the image from Sqlserver convert the byte[] into original format by this way.

public Image GetDataToImage(byte[] pData)
        {
            try
            {
                ImageConverter imgConverter = new ImageConverter();
                return imgConverter.ConvertFrom(pData) as Image;
            }
            catch (Exception ex)
            {
                MsgBox.Show(ex.Message, "Error", MsgBox.Buttons.OK, MsgBox.Icon.Error);
                return null;
            }
        }

and ultimately set the picturebox image by

//call "GetDataToImage" this function before load the image in picturebox
 pictureBoxCompanyLogo.Image = GetDataToImage((byte[])byteimage);

thanks
