Ionic 2 - Usage of thumbnails and avatar inside ion-slide

In, Ionic 2, inside ‘ion-slide’ doesn’t render avatar and thumbnail images in avatar and thumbnail sizes, instead it displays in bigger sizes.

My code:

Cannot we use avatar inside ion-slide in ionic 2?

You have to load thumbnails to display them.
Ionic will not resize your pictures. But you can do it with css.
For example :

ion-slides {
  img {
    max-height: 100px;
    max-width: 100px;
