Building a folder-based gallery for Hugo

A custom hugo shortcode that builds an image gallery from images inside a folder

Source Code

Image Discovery & Gallery Layout

    <!-- "site root"\layouts\shortcodes\foldergallery.html -->

    <style>
        div.gallery {
            display: flex;
            flex-wrap: wrap;
        }
        div.gallery a {
            flex-grow: 1;
            object-fit: cover;
            margin: 2px;
            display: flex;
        }

        div.gallery a img {            
            height: 200px;
            object-fit: cover;
            flex-grow: 1;
        }

    </style>

    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/fancybox/3.4.0/jquery.fancybox.min.css" />

    <div class="gallery">
        {{ $path := print "content\\" .Page.Dir (.Get "src") }}
        {{ $url  := print .Page.URL (.Get "src") }}
        {{ range (readDir $path)  }}            
            {{ $src := print $url "/" .Name }}                
            <a data-fancybox="gallery" href="{{ $src }}">
                <img src="{{ $src }}">  <br/>            
            </a>
        {{ end }}
    </div>

Fancy Box

<!--
1. Replace theme's jquery with 3.3.1 version
2. Add the fancybox3 script
-->
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/fancybox/3.4.0/jquery.fancybox.min.js"></script>

Usage

  { {< foldergallery src="imgs" >} }

Will create an image gallery with the images in the imgs folder

This is cool. I tried building a vacation image site using this... while I was on vacation, and failed. Wondering if there is a "complete" implementation of this code somewhere in Github or a similar repository?

Hi,
came from Jekyll (switched after two weeks for Hugo and never regret it).

I got your Foldergallery running. OK the DOM elements are created but the images are not loaded. Tried a little bit with the .PageURL but didn't get the URL pointing in my folder directory.

What therm do i have to search for, the Hugo documentation is a mouthful... ;) ???

I would suggest comparing the src attribute of dom elements (imgs) against the actual path of the images in the public folder

That's pretty cool. I'll have to give this a shot.
