Hugo-redlounge add picture on index.html

Hello,

I would like to add a picture on the list.html juste in front of description of my article.

This is an exemple of a french blog : http://blog.nicolargo.com/

I use hugo-redlounge template.

I modified the redlounge.css to add :

.post-sumary {
margin-top: 0.5rem;
margin-lef: 10rem;
}

.post-picture {
margin-top: 0.5rem;
margin-lef: 0rem;
}

And in the index.html i add this :

{{ .Params.banner }} {{ .Summary }}

I’am not a dev so … i tried.

Thanks for your help.
