# hugo-snap-gallery
|
|
|
|
Automagical css image gallery in [Hugo](https://gohugo.io/) using shortcodes. Lightweight, slim and fully local JavaScript.
|
|
|
|
## Features
|
|
|
|
- Custom `{{< snap-gallery >}}` shortcode that allows to display multiple images
|
|
- Two modes:
|
|
- **slideshow** displaying only one image at a time with the ability to navigate
|
|
- **gallery** displaying all selected pictures next to each other
|
|
- All pictures can be expanded on click in a lightbox
|
|
- Manually select the images you want to display, or provide the path to a directory to use all images inside. This can be combined!
|
|
- Next/prev buttons in slideshow and lightbox views
|
|
- The gallery is responsive, images are scaled/cropped to fill 16:10 tiles
|
|
- CSS and JS is automatically loaded the first time you use the `{{< snap-gallery >}}` shortcode on each page
|
|
- Multiple galleries/slideshows per page supported, no interference
|
|
- Automatic rotation of slideshow with a configurable interval. Can also be disabled.
|
|
|

## Installation
|
|
|
|
Use this like an additional Hugo theme, so add it to the `theme` config. Example:
|
|
|
|
```
|
|
theme = [ "hugo-sustain", "hugo-snap-gallery" ]
|
|
```
|
|
|
|
## `{{< snap-gallery >}}` shortcode usage
|
|
|
|
Quickstart:
|
|
|
|
- `{{< snap-gallery src="image1.jpg, image2.png" >}}`: Display these two images in **gallery** mode
|
|
- `{{< snap-gallery src="image1.jpg, image2.png" mode="slideshow" >}}`: Display these two images in **slideshow** mode
|
|
- `{{< snap-gallery src="img/folder1/, image2.png" >}}`: Display all images in the directory `img/folder1` and the single image `image2.png` in **gallery** mode
|
|
|
|
All parameters:
|
|
|
|
- `src`: Must contain either a comma-separated list of paths to images, or a directory path containing images.
|
|
- `lightbox`: Whether a click on an image shall open a lightbox modal. Default: `true`.
|
|
- `aspectratio`: Define the aspect ratio of the images in the slideshow/gallery. Default: `16/10`.
|
|
- `mode`: Can be either `gallery` or `slideshow`. Default: `gallery`.
|
|
- For gallery mode:
|
|
- `columns`: Amount of columns the images are displayed in. Default: `4`.
|
|
- `minwidth`: Minimum width that each image shall have, e.g. `150px` or `30%`. May conflict with the desired amount of columns. Default: `200px`.
|
|
- For slideshow mode:
|
|
- `slideshowwidth`: Width of slideshow, e.g. `300px` or `80%`. Default: `100%`.
|
|
- `slideshowrotate`: Whether the slideshow shall automatically rotate through the images. Default: `true`.
|
|
- `slideshowrotate_timer`: Interval of automatic slideshow rotation (if enabled), in milliseconds. Default: `5000` (5 seconds).
|
|
|
|
**Note: Boolean values (`true`/`false`) must be provided without surrounding `"` characters!** `lightbox=false` disables the lightbox, while `lightbox="false"` does not.

## Credits
|
|
|
|
The original inspiration for this shortcode came from [Li-Wen Yip's easy-gallery](https://github.com/liwenyip/hugo-easy-gallery). The first major version of this was already a 90% rewrite, and the current one has even less to do with it. However, the rewrite took some inspirations from [W3Schools](https://www.w3schools.com/howto/howto_js_lightbox.asp), thanks!
