Hi, first thanks for all your hard work. I've got problems during the configuration of your plugin. When I use

bundle exec jekyll build

this is the result

C:\Users\Gio\Documents\GitHub\uselessdevlog` [master ≡ +3 ~4 -3 !]> bundle exec jekyll build

This is my _config.yml

# Picture Tag Config
picture:
  source: "/images/"
  output: "generated"
  markup: "picture"
  presets:
    main:
        ppi: [1, 1.5]
        attr:
            class: "img-responsive"
            itemprop: "image"
        source_medium:
            media: "(min-width: 992px)"
            width: "550"
        source_default: 
            width: "300"

        source_large:

            width: "750px"
        source_medium:

            width: "550"
        source_default: 
            width: "300"

And my Gemfile

source 'https://rubygems.org'
gem 'github-pages', group: :jekyll_plugins 
gem 'jekyll-picture-tag', '~> 0.3.0', group: :jekyll_plugins

I've tried uninstalling/reinstalling image_magick but it doesn't work.

cmd > convert -version

Do you get an image magick response?

You probably don't have image magick installed.
