Fanart.tv artistthumb images are now the primary source for artist
photos. Up to 5 thumbnails fetched per artist (sorted by community
likes). Falls through to Wikimedia/Wikidata/Wikipedia if fanart.tv
has no images for the artist.
API key handling per fanart.tv project key terms:
- Project key loaded from FANART_TV_API_KEY env var (or build-time
ldflags via fanartTVProjectKey variable)
- Users can provide their own personal key via FANART_TV_PERSONAL_KEY
env var for higher rate limits (sent as client_key parameter)
- Results cached 30 days in explore_cache
- No bulk downloading — only fetched per-artist during index build
Source priority order:
