We extend and improve the result of Makkai and Paré (1989) that the powerful image of any accessible functoris accessible, assuming there exists a sufficiently large strongly compact cardinal. We reduce the required large cardinal assumption to the existence of-compact cardinals for sufficiently large, and also show that under this assumption the-pure powerful image ofis accessible. From the first of these statements, we obtain that the tameness of every Abstract Elementary Class follows from a weaker large cardinal assumption than was previously known. We provide two ways of employing the large cardinal assumption to prove each result—one by a direct ultraproduct construction and one using the machinery of elementary embeddings of the set-theoretic universe.
