Watermark on popup image

[Aw3same]

Is it possible to add a watermark in the big image? I'm trying it in the same way as in the examples, by overriding css, but I cant see my watermark in front of image.

my css is

ng-image-slider .lightbox-div {
  z-index: 12;
  content: "";
  display: block;
  width: 100%;
  height: 100%;
  position: relative;
  top: 0px;
  left: 0px;
  background-image: url("/assets/images/confidential.png");
  background-size: 300px 300px;
  background-repeat: space;
  opacity: 0.9;
}

Thanks in advance

If you want watermark, I suggest using merge-images library here. You can create a watermark png and merge it with your desired images before loading them into ng-image-slider.

ng-image-slider itself hasn't been updated since forever.
