Solution 1

Assuming that your DB accepts NULL values in the column:

C#

byte[] a = null;
if (pictureBox1.Image != null)
    {
    MemoryStream ms = new MemoryStream();
    pictureBox1.Image.Save(ms, pictureBox1.Image.RawFormat);
    a = ms.GetBuffer();
    ms.Close();
    }
cmd.Parameters.AddWithValue("@LogoImage", a);

But if it's null, and your SP doesn't specifically accept a null parameter ...
Check your SP definition.
