We cannot currently display any captions on photos but do plan to look into creating a much better galley in the future.
In the meantime when you click on a photo in the gallery the file name that was given to the photo by the person who uploaded it is shown in the url bar on your browser. If people put the species name and any other information they like, e.g. their name, on the file before uploading it this will show.
When attaching a photo, if you want information displayed, please amend the file name accordingly.
The Photo Gallery can be accessed from the Records tab / Photo Gallery or at the bottom of the Home Page.
