You can easily add sidebar features to Fintech manually. Just for reference this is what we mean by that on the main demo:
1. First add an image to the Media section of WordPress. The ones in the demo are 240 x 180px. Note the URL generated.
2. Next go to Appearance > Widgets and add a text widget to the Pages Sidebar Widget Area. This is what is used in the demo:
Title:
[leave blank]
Content:
<a href="#">
<div class="image">
<img src="http://fintech.commercegurus.com/wp-content/uploads/2016/04/fintech_sidebar_feature_1.jpg"/>
</div>
<div class="text">
