Failing to read any exif data

[NiklasEi]

I am having trouble getting any exif data using this plugin. Following the example of the readme I use:

{% capture model %}
    {% exiftag model, assets/images, assets/images/image.jpg %}
{% endcapture %}

Checking the exif data in the terminal (identify -verbose image.jpg | grep "exif:") gives me a huge list of values including the model tag. But using exiftag I keep getting an empty string from {{ model | inspect }}. I tried adding the path to the config or passing nil, since the second parameter is the exact path to the file, but that changes nothing.

Is there anything I might be missing? This plugin should still work, right?

Hi @NiklasEi

So I am very late with an answer. Not sure if this is still helpful after months. I haven't used this plugin myself since years. But I believe the third parameter should be just the image filename, not the whole path, so something like

{% exiftag model, assets/images, image.jpg %}

When I wrote the plugin, I always used it by defining the img filename in the YAML front matter and the sources in the config file, so I used it like this: {% exiftag model %}.

I do believe the plugin should be still working, but I cannot guarantee. If it works for you I would be very glad if you could comment here to let others know.

I am not sure, but this might be as well an issue with how exifr is used in this plugin that is solved in this PR I never got around to merge and release: #6

Hi @benib

Thanks for the answer. As far as I remember I could not fix the issue using this plugin and ended up writing my own one ^^ (see jekyll-exif-data)

It uses filters instead of a tag, but the interaction with exifr should be the same. I could compare our implementations and see if something comes up.

Looks like the only difference is requiring exifr/jpeg like in #6. You could then also change the dependency in your gemspec to .add_dependency "exifr", "~> 1.3".
