Attribution for player headshots and other images sourced from third-party catalogs.
Some player headshots — particularly for lower-tour ATP/WTA tennis players — are sourced from Wikimedia Commons and resolved via Wikidata. These images are licensed under Creative Commons Attribution-ShareAlike 4.0 (a small number are CC-BY-4.0). 4rho displays them as small circular avatars under the implementation guidance for thumbnails published by Wikimedia Commons.
Per-image authorship is recorded on each file's Commons page. To find the credit for a specific photo, hover the player's avatar to see the source URL — clicking through opens the canonical Commons file page where the photographer, date, and full license terms are documented.
Most player headshots and team logos are served by ESPN's public CDN (a.espncdn.com) and are used under their public-API terms. No additional attribution is required for ESPN-hosted assets.
