What if you just read once:

using (SqlConnection conn = new SqlConnection(ConnectionString))
{
    conn.Open();

    string sql = @" SELECT id, name, path FROM Images where id = @id";

    using (SqlCommand comm = new SqlCommand(sql, conn))
    {
        comm.Parameters.AddWithValue("@id", id);           

        using (var reader = await comm.ExecuteReaderAsync())
        {
            if (!reader.Read())
                 throw new Exception("Something is very wrong");

            int ordId = reader.GetOrdinal("id");
            int ordName = reader.GetOrdinal("name");
            int ordPath = reader.GetOrdinal("path");

            image.Id = reader.GetInt32(ordId);
            image.Name = reader.GetString(ordName);
            image.Path = reader.GetString(ordPath);

            return image;
        }
    }
}

P.S.: I have also changed select statement to select only required fields and wrapped reader in using statement.
