Answer 1

give custom name to tabIcon like

<ion-tab [root]="MenuPage"
       tabsHideOnSubPages="true"
       tabIcon="customicon"
       tabTitle="Menu">
</ion-tab>

and in css:

.ion-ios-customicon-outline,
.ion-ios-customicon,.ion-md-customicon,.ion-md-customicon-outline {
  content: url('imageurl');
}

Answer 2

Finally I find a solution ! I just write in the created DOM.

I do like this :

updateAccountTab() : void {
      let array = document.getElementsByClassName('tabbar');
      let tabbar = array[0];
      let element = tabbar.childNodes[tabbar.childElementCount-1];
      if(element) {
          element.removeChild(element.childNodes[1]);
          let img = document.createElement("img");
          img.setAttribute("class", "tab-icon-custom tab-button-icon icon icon-md");
          img.setAttribute("src", this.pdata.user.profile_thumbnail);
          element.insertBefore(img, element.childNodes[1]);
      }
  }
