Since I had a hard time finding a simple solution, I thought I should post How i worked out this issue.
- In your page, use the drag and drop to insert your image.
- Click on the image and choose “convert to html” convert it.
- In the resulting html wrap it with the following code:
<ion-scroll zooming="true" direction="xy"> </ion-scroll>
It’s not pretty, but it does the job.
