        {
            OpenFileDialog fileOpen = new OpenFileDialog();
            fileOpen.Title = "Open Image file";
            fileOpen.Filter = "JPG Files (*.jpg)| *.jpg";

            if (fileOpen.ShowDialog() == DialogResult.OK)
            {
                picImage.Image = Image.FromFile(fileOpen.FileName);
            }
            fileOpen.Dispose();

OpenFileDialog open = new OpenFileDialog();
open.Filter = "Image Files(*.jpeg;*.bmp;*.png;*.jpg)|*.jpeg;*.bmp;*.png;*.jpg";
if (open.ShowDialog() == DialogResult.OK)
{
    textBox10.Text = open.FileName;
}
cn.Open();
string image = textBox10.Text;
Bitmap bmp = new Bitmap(image);
FileStream fs = new FileStream(image, FileMode.Open, FileAccess.Read);
byte[] bimage = new byte[fs.Length];
fs.Read(bimage, 0, Convert.ToInt32(fs.Length));
fs.Close();
SqlCommand cmd = new SqlCommand("insert into tbl_products(Product_image) values(@imgdata)", cn);
cmd.Parameters.AddWithValue("@imgdata", SqlDbType.Image).Value = bimage;
cmd.ExecuteNonQuery();
cn.Close();

To allow users to select files in a Windows Forms application you should look into using the OpenFileDialog class.

To use the dialog on your form you will need to find it in the toolbox in Visual Studio and drag it on to your form.

Once associated with the form you can then invoke the dialog from your code like so:

if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    string selectedFile = openFileDialog1.FileName;
}

You can then use the file path to perform whatever task you wish with the file.

Note: You can use the FileDialog.Filter Property to limit the type of file extensions (images in your case) the user can select when using the dialog.

It's note clear where you are going to upload your image. If you just want to use an image in a simple desktop application you can use OpenFileDialog to allow a user to select an image file. And then you can use this image path in you application. If you you want to upload this image to database you can read this image into memory using something like FileStream class.
