Use ion spinner while img loads

Like the title says, is there a way to know when an img is currently loading so I can make use of the ion-spinner?

Here is what I currently have…

    <ion-item *ngFor="let item of items" button menuClose (click)="pushNav(item.table, item.ID)">

      <ion-thumbnail *ngIf = "item.noimg; else elseBlock" item-start>
        <img src="{{item.featured}}">

      <ng-template #elseBlock>

          <img src="{{[0]}}">


This is what I am looking for…

          <ion-spinner *ngif="imgIsLoading">

          <img *ngif="imgIsDoneLoading" src="{{[0]}}">

…or if there is a similar way please do share!

You could lazy load your images using something like this
