ULRICH LAMSFUSS, ''The Raw and the Cooked,'' Lombard-Freid, 531 West 26th Street, (212) 967-8040 (through April 5). This Berlin painter copies photographs from fashion, news, travel and other sorts of magazines. A gallery release and two portraits of Andy Warhol, one a copy of the other, suggest that he has ulterior conceptual motives, but his faithfully nondescript renderings of fighting elephants, a movie zombie and a herd of wild horses leave one uncertain about exactly what he is up to (Johnson).
