示例1: dbImageGet
// dbImageGet gets an ImageBaseInfo object from the database.
// The argument fingerprint will be queried with a LIKE query, means you can
// pass a shortform and will get the full fingerprint.
// There can never be more than one image with a given fingerprint, as it is
// enforced by a UNIQUE constraint in the schema.
