How Paris's Public Image Archives Fell Into a Duplicate Crisis — and What's Being Done to Fix It

Paris's municipal image library contains an estimated 340,000 digitised photographs, heritage drawings and promotional visuals — and a significant share of them appear more than once. The City of Paris's Direction de la Communication confirmed last autumn that an internal audit had flagged widespread duplication across its asset management systems, a problem that had been accumulating since the early 2000s but accelerated sharply after the Paris 2024 Olympic Games, when dozens of separate agencies simultaneously uploaded event documentation to shared servers without a unified tagging protocol.

The issue matters now because the city is mid-way through a broad digital infrastructure overhaul tied to the Grand Paris Express project and the ongoing Seine riverbank regeneration. Both programmes generate enormous volumes of commissioned photography — construction milestones, public consultation sessions, ribbon-cutting ceremonies — that feed into press offices, planning applications and public-facing websites. When the same image exists under four different file names and three different metadata entries, it does not merely waste storage. It creates contradictory licensing records, slows archive searches and, in at least one documented case during the 2024 Games preparation, caused a copyrighted aerial photograph of the Stade de France to be republished without the original agency's authorisation because a duplicate entry had stripped the rights metadata.

The Anatomy of the Problem

The duplication crisis has roots in how Paris grew its digital infrastructure piecemeal. The Bibliothèque historique de la Ville de Paris on Rue de Rivoli maintained its own cataloguing system, as did Paris Musées, the umbrella body covering fourteen city-owned collections including the Musée Carnavalet in the Marais. Neither system spoke fluently to the Direction de la Communication's asset database, nor to the separate repositories maintained by Apur, the Paris urban planning agency that has been producing mapped and photographic documentation of the capital since 1967. Each body had legitimate reasons to hold its own copies: provenance, conservation standards and internal workflow all differed. But the result, visible by 2023, was a sprawling, inconsistent visual estate that independent IT consultants described in a published tender document as containing duplication rates of between 18 and 25 percent across shared categories.

The 2024 Olympics made it worse before anyone could make it better. Paris 2024 organisers worked with at least seven different official photography contractors, each delivering assets through separate portals. When the games ended and the legacy-activation phase began — handing back venues, managing post-event communications, opening the Seine bathing sites at the Berges de Seine and near the Pont d'Iéna — images migrated across systems with minimal quality control. A formal deduplication tender was issued by the city's IT procurement arm, the Agence Parisienne du Numérique, in March 2026, with a project completion deadline set for the first quarter of 2027.

What Comes Next

The Agence Parisienne du Numérique's March 2026 tender specifies the adoption of perceptual hashing technology, which identifies visually identical or near-identical images regardless of file name, format or resolution, combined with a centralised DAM — digital asset management — platform that all subscribing city bodies would access through a single permissions structure. Apur and Paris Musées are listed as mandatory integration partners in the tender documents. The Bibliothèque historique is listed as a secondary phase participant, reflecting the additional complexity of its heritage collection rights.

For journalists, researchers and communications professionals who regularly pull images from the city's public portals — including the widely used Paris en Images database — the practical change will be a cleaner search experience and, crucially, reliable licensing data attached to every file. Photographers who work on contract with city departments have been told that the new system will include automated rights-expiry alerts, addressing a complaint that has circulated in the professional photography community since at least 2021.

The tender budget has not been made public. The March 2026 documents state only that the project falls under a framework agreement valued below the EU public procurement threshold that requires full open tender, suggesting a figure beneath the €215,000 ceiling applicable to service contracts in France. Whether the first-quarter 2027 deadline holds will depend heavily on how quickly Apur and Paris Musées can complete their legacy data mapping — work that both agencies are understood to have started but not yet finished.
