If you are already in the main context you do not need "context". See too if you are taking the name of the photo correctly. I tested it this way and it worked perfectly:

String nomeFoto = "nome_da_foto"; //sem o PGN, JPG, etc...
int drawableId = getResources().getIdentifier(nomeFoto, "drawable", getPackageName());

imagem.setImageResource(drawableId );
