Hi Diego,
Not sure if the approach I took was the most elegant, but since you asked here's what I did to achieve the results I was after.
1. Create a new widget or clone the existing icon link widget.
2. Add two new options schemas, one for the image URL and the other for the link. In my case both of them were strings.
3. Bind the data to the HTML
<div>
<h3>{{::options.title}}</h3>
<a href="{{::options.imglink}}" target="_blank">
<img src="{{::options.testimg}}" alt="" />
</a>
</div>
As you can see, since the link to the image is a string you will have to upload the image to servicenow first and then copy the filename with extension and paste into the imagelink instance option. This work as expected for me. Let me know if you have any questions.
