Well this may not be what you wanted, but I got a pseudo filter over the image

img {
  display: block;
  z-index: 1;
}

div.wrapper {
  position: relative;
  display: inline-block;
}

/* Filter */
div.over {
  content: "";
  background: rgba(0,200,0,0.5);
  position: absolute;
  height: 100%;
  width: 100%;
  top: 0;
  left: 0;
  z-index: 2;
}
