ASP.NET (C#) Question

System.Data.SqlClient.SqlException' has occured

I'm trying to store images on my ASP.NET web forms website, in an 'Images' folder.

Here is the code behind my submit button:

protected void btnSubmit_Click(object sender, EventArgs e)
//Get Filename from fileupload control
string filename = Path.GetFileName(fileuploadimages.PostedFile.FileName);
//Save images into Images folder
fileuploadimages.SaveAs(Server.MapPath("Images/" + filename));
//Getting dbconnection from web.config connectionstring
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["BallinoraDBConnectionString1"].ToString());
//Open the database connection
//Query to insert images path and name into database
SqlCommand cmd = new SqlCommand("Insert into Group_Images(ImageName,ImagePath) values(@ImageName,@ImagePath)", con);
//Passing parameters to query
cmd.Parameters.AddWithValue("@ImageName", filename);
cmd.Parameters.AddWithValue("@ImagePath", "Images/" + filename);
//Close dbconnection

Here is the error message I'm receiving
