Andromeda is a lightweight photojournal & blog theme designed for Zola.
With built-in support for galleries and some options for customization, Andromeda is designed for photojournalism without complications.

Post demo:

Assuming you already have a site set up (see the Zola guide for setting up a site),
themes directory in the root of your site if it does not already exist.git clone https://github.com/Pixadus/andromeda-theme themes/andromeda
config.toml file found in themes/andromeda/config.toml or this repository within your own config.toml.theme = andromeda in your config.toml file.To create a new post, create a .md file within /content, with the header format:
+++
title = "Post title"
date = 2023-04-25
description = "Post description"
extra = {header_img = "image-url"}
+++
Note: The +++ are necessary.
The header_img field is the image shown on the homepage of the blog and in the heading of each page. It can be a remote URL or local - if local, by default this will be files stored in the static folder, or /images in the URL.
Galleries can be set up by using the following template in your Markdown file:
<div class="gallery">
<a href="original_photo1.jpg" data-ngthumb="thumbnail_photo1.jpg"></a>
<a href="original_photo2.jpg" data-ngthumb="thumbnail_photo2.jpg"></a>
</div>
For more or less photos, use <a href> tags. Flickr provides a good hosting option as it automatically generates thumbnails for you.
Andromeda supports custom navbar links - see config.toml for an example. You may also set a custom favicon.ico though config.toml.
If you wish to customize the design of the gallery, basic Javascript knowledge will be necessary. Andromeda uses nanogallery2 by default - the documentation can be found here. Customizations to the gallery design are done within the {%/* macro pagefooter() */%} block within /templates/macros.html.
By default, this script is divided into three sections (indicated by item==): single-image, two-image and three+ image gallery setups.
The demo images used included Antelope Canyon by Anishkumar Sugumaran and Bryce Canyon by Marco Isler.
