Use images instead of icons in "features" templates

I know that this is not a just hugo but a general markdown? issue
Maybe anyone can help me though

I’d like to use images instead of icons.

In /data/textmain/no1 I have written:
image: "/img/green.jpg" instead of icon: "fa fa-envelope-o"

In layouts/partials/textmain.html

(edit: cannot insert the code)

instead of

<div class="icon">
<i class="{{ .icon }}"></i>

src="{{ .image | absURL }}" solved it for me
