How to position a button at the bottom of a slide - Ionic

I have the following slides of images:

  <ion-slides style="margin-top: 30px; margin-bottom: 30px" pager="true" [options]="slideOpts">
    <ion-slide *ngFor="let image of imageURLs">
      <div (click)="openZoomedImage(image.fullURL)">
        <img [src]="image.fullURL" alt=”slide-1”/>
      <ion-button size="small" color="danger"  (click)="deleteImage(image.imageName)">Delete</ion-button>

However I am wondering how I can make the delete button for each image at the bottom of the slides?

Thank You
