angular - <img>: Unsafe value used in a resource URL context

Question

Since upgrading to the latest Angular 2 release candidate, my img tags:

<img class='photo-img' [hidden]="!showPhoto1" src='{{theMediaItem.photoURL1}}'>

are throwing a browser error:

ORIGINAL EXCEPTION: Error: unsafe value used in a resource URL context

The value of the url is:

http://veeu-images.s3.amazonaws.com/media/userphotos/116_1464645173408_cdv_photo_007.jpg

EDIT:

I have tried the suggestion made in the other solution that this question is supposed to be a duplicate of but I am getting the same error.

I have added the following code to the controller:

import {DomSanitizationService} from '@angular/platform-browser';

@Component({
  templateUrl: 'build/pages/veeu/veeu.html'
})
export class VeeUPage {
  static get parameters() {
    return [[NavController], [App], [MenuController], [DomSanitizationService]];
  }

  constructor(nav, app, menu, sanitizer) {

    this.app = app;
    this.nav = nav;
    this.menu = menu;
    this.sanitizer = sanitizer;

    this.theMediaItem.photoURL1 = this.sanitizer.bypassSecurityTrustUrl(this.mediaItems[1].url);
  }

I am still getting the same error message.

EDIT2:

I have also changed the html to:

<img class='photo-img' [hidden]="!showPhoto1" [src]='theMediaItem.photoURL1'>

I still get the same error message

Pipe

// Angular
import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml, SafeStyle, SafeScript, SafeUrl, SafeResourceUrl } from '@angular/platform-browser';

/**
 * Sanitize HTML
 */
@Pipe({
  name: 'safe'
})
export class SafePipe implements PipeTransform {
  /**
   * Pipe Constructor
   *
   * @param _sanitizer: DomSanitezer
   */
  // tslint:disable-next-line
  constructor(protected _sanitizer: DomSanitizer) {
  }

  /**
   * Transform
   *
   * @param value: string
   * @param type: string
   */
  transform(value: string, type: string): SafeHtml | SafeStyle | SafeScript | SafeUrl | SafeResourceUrl {
    switch (type) {
      case 'html':
        return this._sanitizer.bypassSecurityTrustHtml(value);
      case 'style':
        return this._sanitizer.bypassSecurityTrustStyle(value);
      case 'script':
        return this._sanitizer.bypassSecurityTrustScript(value);
      case 'url':
        return this._sanitizer.bypassSecurityTrustUrl(value);
      case 'resourceUrl':
        return this._sanitizer.bypassSecurityTrustResourceUrl(value);
      default:
        return this._sanitizer.bypassSecurityTrustHtml(value);
    }
  }
}

Template

{{ data.url | safe:'url' }}

That's it!

Note: You shouldn't need it but here is the component use of the pipe

  // Public properties
  itsSafe: SafeHtml;

  // Private properties
  private safePipe: SafePipe = new SafePipe(this.domSanitizer);

  /**
   * Component constructor
   *
   * @param safePipe: SafeHtml
   * @param domSanitizer: DomSanitizer
   */
  constructor(private safePipe: SafePipe, private domSanitizer: DomSanitizer) {
  }

  /**
   * On init
   */
  ngOnInit(): void {
    this.itsSafe = this.safePipe.transform('<h1>Hi</h1>', 'html');
  }
