Ionic 3 not functioning - directive nor programmatically

[jmmclean]

Please provide you version information :

Dependency	Version
ionic	3
angular	4
ionic-img-viewer	2.6.1

Have you checked...

• [x] That npm install returns no warning ?
• [ ] Doing a purge of your node_modules folder ?

Symptom:

When executing as per readme.md, I am unable to enlarge an image upon click. This issue is observed for directive and js/ts

DEBUG:

No Errors displayed from directive usage, but no functionality either

Stack Trace from js/ts:

@jmmclean According to the documentation you need to inject the ImageViewerController via constructor. Try moving the ImageViewerController instantiation into the constructor like this:

  constructor(private _imageViewerCtrl: ImageViewerController) {

Im going to go ahead and blame coders block on this one...i ended up just making page and importing IonicImageViewerModule. Thanks for the response!
