Uploading Image File to a DataBase

Question

Somebody know how to upload a Image File to a DataBase. The file is selceted by the user by a OpenFileDialog.
if (OpenFileDialog1.Show()==DialogResult.Ok)
{
Image img = Image.FromFile(OpenFileDialog1.FileName)
//Uploading img to the DataBase
}
I have the next wrong code to Upload img to the DataBase:
SqlCommand InsertCommand = new SqlCommand("INSERT TO MyTable (ImageColumn) VALUES (@Image)",MyConnacetion);
InsertCommand.Parameters.Add("@Image",img); //This line throws an error
MyConnection.Open();
InsertCommand.ExecutQuery();
MyConnection.Close();
When I add the paremeter, the next exception is thrown:
"Index (zero based) must be greater than or equal to zero and less than the size of the argument list."
Any Idea?
Thanx in advance.

I founf the next code to upload the image:
FileStream imgStream = new FileStream(ImagePath,FileMode.Open);
long DataLength = imgStream.Length;
byte[] imgData = new byte[DataLength];
SqlCommand InsertCommand = new SqlCommand("INSERT TO MyTable (ImageColumn) VALUES (@Image)",MyConnacetion);
InsertCommand.Parameters.Add("@Image",imgData);
MyConnection.Open();
InsertCommand.ExecutQuery();
MyConnection.Close();
Before I upload the image I show it in a PictureBox And now throws the next exception:
The process cannot access the file "C:\SipidermanFace.bmp" because it is being used by another process.
Somebody help me plase!!
