1. I think this logic would be better placed in themes/vocabulary_theme/templates/macros/authors_gravatar.html
2. Please include the image in the PR per previous feedback:

   please find an openly licensed or public domain image that can be included in this repository

Hi there! I was trying to figure out exactly how to include the image in the PR. I'm aware that the image has to be open source and secure but I'm not seeing a folder of a .yaml file to add the image to make it available locally (on github). Could you please indicate to me how I could go about doing this?

Also, I want to ensure that the image will be available indefinitely if needed without any interruptions, so I would like to not have to use the direct link.

Thank you in advance!
