Hi Tom
Yes it is possible to add an image in the text area.
Simply write your own excerpt for the selected page in the page editor, and add html markup for an image
example:
<img src="http://www.yourwebsite.com/wp-content/uploads/2017/09/image-name.jpg" />
Add text before and/or after the image markup if you want.
The pro version – Trusted Pro – also allows you to upload your own images in place of the icons.
Hope this helps.
