Investigate how we store and serve reduced images for the distribution of species

As part of the species information page we want to show maps of the distributions of those species. These will also be overlays on the map view and users can download the full data from there - however here on the information page we want to show a smaller static image and be able to download that.

For the investigation we need to consider how an editor would upload these static images and associate them with a partcular species information entry. At the moment we commit them to the public folder in the code base but this isn't changable by an editor in the longer term.

Acceptance criteria:

• The output of the investigation is documented here.
• New stories are written to cover the implementation.

Start by tracing how reduced species-distribution images are currently committed to and served from the public folder, and how species information pages and map overlays reference them. Document options for editor uploads and associating images with species entries, then record the investigation here and write the follow-up implementation stories.
