Tag your question properly. WinForms, WPF ...

The internet abounds with sample code that does this. Online articles will contain more detail than a forum reply, every time.

Insert Step
//---------------
MemoryStream ms = new MemoryStream();
PBoxGuestImage.Image.Save(ms, ImageFormat.Jpeg);
Byte[] PicArray = new Byte[ms.Length];
ms.Position = 0;
ms.Read(PicArray, 0, PicArray.Length);

CMD.CommandText = "Insert Into TestTable(TestImage) Values (@ParTestImage)"
CMD.Parameters.AddWithValue("@ParTestImage", PicArray);
//---------------
this works great

Retrieve Step

Image NewImage;
byte[] content = (byte[])TestReader["TestImage"];
TestPictureBox.Image = null;
using (MemoryStream stream = new MemoryStream(content, 0, content.Length))
{
stream.Write(content, 0, content.Length);
NewImage = Image.FromStream(stream, true); //at this line i get the exception
}
TestPictureBox.Image = NewImage;
