Display image in projects list

[vanillaiice]

Hi Hugo,

Firstly, thank you for making this great hugo theme.

In the 'Projects' tab of my site, I am trying to display a thumbnail for each project (just like in yours).
However, I can't seem to find the proper key name in yaml front matter of the page.

Here is my _index.md:

+++
hideDate = true
hideAuthor = true
hideLastMod = true
+++

# Projects

And here is one of my projects (content/project/dtb.md):

+++
title = 'DTB (Dodge The Balls)'
date = 2024-04-08T05:35:12+03:00
draft = false
headline = 'Simple game where you dodge moving balls, made with Lua and Löve2D.'
image = '/images/face.jpg'
+++

## DTB

Finally, here is what my projects tab currently looks like:

Any help would be greatly appreciated !
