This is basic HTML question that would be better answered in and HTML reference site.
What you are describing is just an image tag in a link tag. The basic structure would look like
For just a link image:
<a href=”LinkURL“><img src=”ImageUrl” /> </a>
For just a link text:
<a href=”LinkURL“> Text </a>
So a clickable icon followed by text followed by clickable number would looklike
<a href=”LinkURL“><img src=”ImageUrl” /> </a> Text after Image <a href=”LinkURL“> Clickable Phone Number </a>
