ADO.NET :: Error 'String Or Binary Data Would Be Truncated" When Trying To Upload An Image

I am getting the error: String or binary data would be truncated. The statement has been terminated. when trying to upload an image. What would cause this? my code is:

protected void Button1_Click(object sender, EventArgs e)
{
if (IsPostBack)
{
HandleUploadedFile();
}
string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
System.Data.SqlClient.SqlConnection sqlConnection1 =
new System.Data.SqlClient.SqlConnection(connectionString);
System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = "INSERT INTO picstosort (imageurl, useraddy) VALUES (@imageurl, @useraddy)";
cmd.Parameters.AddWithValue("@imageurl", Label5.Text);
cmd.Parameters.AddWithValue("@useraddy", TextBox1.Text);
cmd.Connection = sqlConnection1;
sqlConnection1.Open();
cmd.ExecuteNonQuery();
sqlConnection1.Close();
if (TextBox1.Text != null)
{
string strTo = TextBox1.Text;
string strFrom = "noreply@test.com";
string strSubject = "Picture Uploaded";
SmtpMail.Send(strFrom, strTo, strSubject,
"Thank you for uploading your picture! ");
}
}
