Problems implementing lib ng2-img-max!

I installed ng2-img-max for the purpose of resizing images. I want each submitted image to be resized to a predefined width and length. I see that most people use ng2-img-max when developing with 2/4 angular. I tried using this lib and then faced the following error:

Error: Uncaught (in promise): Error: No provider for Ng2PicaService

This error informs that the service name needs to be placed on the providers, the problem is that in my project I did not create any service with that name, I am guiding myself through this tutorial below;

Resizing Images in the Browser in Angular With ng2-img-max

I have created a module to store all the services related to the implementation of the image resizer as you can see below;

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ImgMaxPXSizeService } from './img-maxpx-size.service';
import { ImgMaxSizeService } from './img-max-size.service';
import { Ng2ImgMaxService } from './ng2-img-max.service';
import { ImgExifService } from './img-exif.service';
import { Ng2PicaService } from '../../../node_modules/ng2-pica';

@NgModule({
  imports: [
    CommonModule
  ],
  declarations: [],
  providers: [
    ImgMaxPXSizeService,
    ImgExifService,
    ImgMaxSizeService,
    Ng2ImgMaxService
]
})
export class ImgMaxModule { }

//https://github.com/bergben/ng2-img-max

And the module I posted in the app.module.ts

As you can see below;

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    HttpModule,
    RouterModule,
    SharedModule,
    RestaurantModule,
    AdminModule,
    ImgMaxModule,// >>>>>>> modulo de imagens
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

How could I circumvent this problem?

I think that only people who have already tampered with this lib will be able to help me.

This is my complete project in the github repository.
