9 years ago I believe you need to define presets, so something like this:
picture:
source: "assets/imgs/_fullsize"
output: "generated"
markup: "picture"
presets:
default:
ppi: [1, 1.5]
source_medium:
media: "(min-width: 40em)"
width: "600"
height: "300"
source_default:
width: "300"

9 years ago I did it:
picture:
source: "assets/imgs/_fullsize"
output: "generated"
markup: "picture"
presets:
default:
ppi: [1, 1.5]
source_medium:
media: "(min-width: 40em)"
width: "600"
height: "300"
source_default:
width: "300"Unfortunately the behavior is exactly the same:

I've looked through a few of the most recent commits and I couldn't find anything that would cause that stack trace. Could you try installing the gem and post an updated stack trace?

9 years ago I just copied https://raw.githubusercontent.com/robwierzbowski/jekyll-picture-tag/master/lib/jekyll-picture-tag.rb to _plugins folder of my blog. Shall I install something else in addition to it?
I tried to switch to gems but everything stopped to work for me (not a problem with your plugin but something weird with Gentoo Jekyll setup). Can I somehow put your code to my setup without using gems?

9 years ago I had the same error and it was because of the wrong indenting in config.yml: source_medium: should be indented to under ppi otherwise it's interpreted as a preset, not a property of the default preset (same goes for all the subsequent lines. It's a copy-paste thing.

9 years ago Thank you! It was my case also.
Working config:
picture:
source: "_assets/imgs/_fullsize"
output: "generated"
markup: "picture"
presets:
default:
ppi: [1, 1.5]
source_medium:
media: "(min-width: 40em)"
width: "600"
height: "300"
source_default:
width: "300"
When I try to use the picture tag I am constantly getting this error:
Liquid Exception: undefined method `[]' for nil:NilClass in _drafts/JekyllAnchors.md/#excerpt
Trace:
My source file has basically one line in the content section:
{% picture anchor.jpg %}
Jekyll version: 2.5.3
_config related to picture:
I use redcarpet processor and re-define excerpt_separator.
