Can I use any property name for image path?

Not only 'url' that shown in the example?

I'll make it customizable so that a method on the provider can be changed to return the image path in any way you want.

With v0.3.0, you can now do it like this:

angular.module('app').config(function (LightboxProvider) {
  LightboxProvider.getImageUrl = function (image) {
    return image.otherPropertyName;
  };
});
