See here: Why do I get a "Parameter is not valid." exception when I read an image from my database?[^] - it's Sql Server based, but it's exactly the same problem (and solution) with MySql.

And did you read the bit at the bottom?
"Before I close...
No, you can't retrieve the image data for the images you already stored wrongly - you will have to delete them all, and save them to the DB correctly!"

Because if you didn't...

Do have a look at the following article.

I hope it will solve your problem. :)

C#

string query1 = "Select * from members where ID='";
           query1 = query1 + txtid.Text + "'";
           cmd = new MySqlCommand(query1, con);
           MySqlDataReader d1 = cmd.ExecuteReader();
           while (d1.Read())
           {
               try
               {
                   byte[] data = (byte[])d1["image"];
                   using (MemoryStream stream = new MemoryStream(data))
                   {
                       pictureBox1.Image = new Bitmap(stream);
                   }
