            DialogResult result = openFileDialog1.ShowDialog();
            openFileDialog1.Filter = "JPEG Files(*.jpeg)|*.jpeg|PNG Files (*.png )|*.png |JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif";

The first thing I'd do if I got the actual error "Could not find ... etc" would be to look at my code and change something THERE. Perhaps shorten the "path", change the directory to a different "path", check the properties of some of the "path" statements. Then, of course, there's always the pathetic failure to create the target folder for this "path". But I have only this code here to qualify this so descriptively.

C#

cmd.CommandText = "insert into student_info values('" + textBox1.Text + "','" + img_path.ToString() + "','" + textBox2.Text + "','" + textBox3.Text + "','" + textBox4.Text + "','" + textBox5.Text + "','" + textBox6.Text + "')";

Not a solution to your question, but another problem you have.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.
