SQLiteConnection cnn = new SQLiteConnection("Data Source=C:tempdatabase.s3db");
cnn.Open();
SQLiteCommand mycommand = new SQLiteCommand(cnn);
mycommand.CommandText = "INSERT INTO images (image_name, tags, relevance) VALUES ("Example Image åäö.jpg", "test", 3)";
mycommand.ExecuteNonQuery();
cnn.Close();
cnn.Dispose();

private IDbDataParameter AddParameter(IDbCommand command, string paramName, DbType type, object value)
{
    IDbDataParameter parameter = command.CreateParameter();
    parameter.ParameterName = paramName;
    parameter.DbType = type;
    if (value != null)
        parameter.Value = value;
    else
        parameter.Value = DBNull.Value;
    command.Parameters.Add(parameter);
    return parameter;
}

mycommand.CommandText = "INSERT INTO images (image_name, tags, relevance) VALUES (@image_name, @tags, @relevance)";
AddParameter(mycommand, "@image_name", DbType.String, "Example Image åäö.jpg");
AddParameter(mycommand, "@tags", DbType.String, "Test");
AddParameter(mycommand, "@relevance", DbType.Int32, 3);
