Solution 1

You're lucky: most people mess up well before that and only find out once they have loaded the DB full of what they think are images, but aren't!

Same problem though, and same solution: Why do I get a "Parameter is not valid." exception when I read an image from my database?[^]

Solution 2

Create a MemoryStream and save the Image to it, then you can convert the MemoryStream to a byte array and pass that to your SQL parameter:

C#

using (MemoryStream ms = new MemoryStream())
{
    pictureBox1.Image.Save(ms, ImageFormat.Png);
    command.Parameters["@imgmodel"].Value = ms.ToArray();
}
