Description of problem:
Step 1: Perform a search of observations (/observations).
Step 2: Navigate to the Species tab.
Step 3: Find a listed taxon where the taxon image is licensed under CC0.
Step 4: Hover over the CC0 text.
The hover text will display as “By Unknown no rights reserved (CC0)”, rather than crediting the actual author. For example, while the above screenshot shows “Unknown” as the author, the photo page shows Richard Fuller as the author.
