It uses [RMagick](http://rmagick.rubyforge.org/) to create thumbnails. 4 | 5 | This plugin is quite minimalist. It generates galleries with no pagination, no sub-galleries, and no descriptions. [See my gallery](http://geoff.greer.fm/photos/) for an example of what it looks like. 6 | 7 | [![Gem Version](https://img.shields.io/gem/v/jekyll-gallery-generator.svg)](https://rubygems.org/gems/jekyll-gallery-generator) 8 | 9 | [![Build Status](https://travis-ci.org/ggreer/jekyll-gallery-generator.svg?branch=master)](https://travis-ci.org/ggreer/jekyll-gallery-generator) 10 | 11 | [![Floobits Status](https://floobits.com/ggreer/jekyll-gallery-generator.svg)](https://floobits.com/ggreer/jekyll-gallery-generator/redirect) 12 | 13 | 14 | ## Usage 15 | 16 | 1. Install the `jekyll-gallery-generator` gem, either by running `gem install jekyll-gallery-generator` or by adding `gem 'jekyll-gallery-generator'` to your `Gemfile` and running `bundle`. 17 | 18 | 2. Add `jekyll-gallery-generator` to the plugins list in your `_config.yml`: 19 | 20 | ```yaml 21 | plugins: 22 | - jekyll-gallery-generator 23 | ``` 24 | 25 | 3. Copy your image directories into `jekyll-site/photos/`. Here's what my directory structure looks like: 26 | 27 | ```bash 28 | $ ls jekyll-site/photos 29 | best/ chile_trip/ japan_trip/ 30 | $ ls jekyll-site/photos/chile_trip 31 | IMG_1039.JPG IMG_1046.JPG IMG_1057.JPG 32 | ``` 33 | 34 | 4. Run `jekyll build` and be patient. It can take a while to generate all the thumbnails on the first run. After that, you should have pretty pictures. 35 | 36 | 37 | ## Dependencies 38 | 39 | * [ImageMagick](http://www.imagemagick.org/) 40 | * [RMagick](https://github.com/rmagick/rmagick) 41 | * [exifr](https://github.com/remvee/exifr/) 42 | * [Ruby](https://www.ruby-lang.org) >= 2.1 43 | 44 | ### Install dependencies on OS X 45 | 46 | ```bash 47 | brew install imagemagick rbenv 48 | rbenv install 2.4.0 49 | rbenv global 2.4.0 50 | gem install rmagick exifr 51 | ``` 52 | 53 | ### Install dependencies on Ubuntu 54 | 55 | ```bash 56 | apt install libmagick++-dev 57 | gem install rmagick exifr 58 | ``` 59 | 60 | ## Configuration 61 | 62 | This plugin reads several config options from `_config.yml`. The following options are supported (default settings are shown): 63 | 64 | ```yaml 65 | gallery: 66 | dir: photos # Path to the gallery 67 | symlink: false # false: copy images into _site. true: create symbolic links (saves disk space) 68 | title: "Photos" # Title for gallery index page 69 | title_prefix: "Photos: " # Title prefix for gallery pages. Gallery title = title_prefix + gallery_name 70 | sort_field: "date_time" # How to sort galleries on the index page. 71 | # Possible values are: title, date_time, best_image 72 | thumbnail_size: 73 | x: 400 # max width of thumbnails (in pixels) 74 | y: 400 # max height of thumbnails (in pixels) 75 | # The following options are for individual galleries. 76 | galleries: 77 | chile_trip: 78 | best_image: IMG_1068.JPG # The image to show on the gallery index page. Defaults to the last image. 79 | japan_trip: 80 | best_image: IMG_0690.JPG 81 | name: "日本の旅" # Defaults to directory name, replacing _ with spaces & capitalizing words. 82 | awesome_stuff: 83 | best_image: snaileo_gonzales.jpg 84 | sort_reverse: true # Reverse sort images in gallery. 85 | secret_stuff: 86 | hidden: true # Don't show this gallery on the index page. People must guess the URL. 87 | with_info: 88 | info: 89 | desc: "Gallery Description" # Info fields can be used in custom templates. 90 | ``` 91 | 92 | 93 | ## Overriding layouts 94 | 95 | If you want to customize the templates used by this generator, copy `gallery_index.html` and `gallery_page.html` to your Jekyll site's `_layouts`: 96 | 97 | cp lib/gallery_index.html jekyll-site/_layouts/ 98 | cp lib/gallery_page.html jekyll-site/_layouts/ 99 | -------------------------------------------------------------------------------- /jekyll-gallery-generator.gemspec: -------------------------------------------------------------------------------- 1 | Gem::Specification.new do |spec| 2 | spec.name = "jekyll-gallery-generator" 3 | spec.summary = "Generate galleries with thumbnails for your Jekyll site." 4 | spec.version = "1.2.4" 5 | spec.authors = ["Geoff Greer"] 6 | spec.email = "geoff@greer.fm" 7 | spec.homepage = "https://github.com/ggreer/jekyll-gallery-generator" 8 | spec.licenses = ["Apache-2.0"] 9 | 10 | spec.files = `git ls-files -z`.split("\x0") 11 | spec.require_paths = ["lib"] 12 | 13 | spec.requirements << "imagemagick, >=v6.9 (needed by RMagick)" 14 | 15 | spec.add_runtime_dependency "exifr", "~> 1.3" 16 | spec.add_runtime_dependency "rmagick", "~> 4.1.1" 17 | 18 | spec.add_development_dependency 'jekyll', '~> 3.8', '>= 3.8.3' 19 | spec.add_development_dependency "bundler", "~> 1.6" 20 | end 21 | -------------------------------------------------------------------------------- /lib/gallery_index.html: -------------------------------------------------------------------------------- 1 | --- 2 | layout: page 3 | --- 4 | 15 | {% for gallery in page.galleries %} 16 |
