It is possible yes, with the property tansform: scaleX(..) you do that easily:
img {
  width: 260px;
}
#esquerda {
    -moz-transform: scaleX(-1);
    -o-transform: scaleX(-1);
    -webkit-transform: scaleX(-1);
    transform: scaleX(-1);

Make one with Rotate too (and put an observation so that in the case of arrow, by chance, as it is symmetrical, it works out) :P
