Paris Takes on the Duplicate Image Problem — and It's Ahead of Some Rivals, Behind Others

Paris's municipal digital agency, the Direction de la Transformation Numérique, confirmed last spring that it had begun a systematic audit of the city's official web portals after internal reviews found hundreds of duplicated stock photographs and recycled visual assets cluttering platforms used by millions of residents each year. The problem — banal-sounding but operationally significant — has quietly become a test case for how major European capitals manage their digital estates as they push services online.

The stakes are real. When duplicate or mismatched images appear on official portals — a photo of Berlin's Alexanderplatz on a Paris transport update, say, or a recycled thumbnail appearing across dozens of unrelated public announcements — it erodes trust in the platform and, crucially, creates accessibility failures for visually impaired users relying on alt-text metadata. The issue has sharpened since 2024, as city governments leaned harder into online communication during and after the Paris Olympics, generating a surge in rushed content uploads. The Grand Paris Express construction programme alone feeds dozens of update pages weekly, each requiring original photography or correctly licensed imagery.

What Paris Is Actually Doing

The audit, which began in March 2026, covers paris.fr and several sub-portals including the Île-de-France Mobilités passenger information pages and the Mon Paris digital city card platform. A working group inside the Hôtel de Ville has been tasked with building a centralised image asset library — essentially a controlled repository that flags duplicate file hashes before content goes live. The system is modelled partly on tools already deployed by Amsterdam's Digitale Stad initiative and partially on internal tooling developed for the Paris 2024 Olympics digital communications effort, which had its own strict brand consistency requirements.

In the 11th arrondissement, the mairie's local portal was identified as one of the worst offenders in the initial sweep, with staff uploading the same neighbourhood streetscape image — a shot taken near the Marché de la Bastille — to more than 40 separate event pages between January 2025 and February 2026. That single image, according to internal documentation reviewed by The Daily Paris, had accumulated 23 separate duplicate entries in the content management system.

The city's approach contrasts with London, where the Greater London Authority began a comparable deduplication exercise for its Datastore and public communications portals in late 2023, completing a first-pass cleanup by mid-2024. Berlin's Senate Chancellery launched a similar project in 2025 under its Digitalisierung framework. Both cities moved faster than Paris, partly because their central digital teams had more headcount. Paris's Direction de la Transformation Numérique operates with roughly 140 permanent staff — a figure that city councillors have debated as inadequate given the scale of the capital's digital footprint.

The Broader Race Among Global Capitals

New York City's Department of Citywide Administrative Services flagged duplicate digital asset management as a priority item in its 2025 technology roadmap, allocating $2.3 million toward a unified media library for NYC.gov. That outpaces what Paris has formally budgeted for its image library project, though city officials have declined to specify the exact line-item allocation. Tokyo's metropolitan government, by contrast, has relied primarily on vendor-side deduplication built into its Salesforce-based content platform since 2023 — a cleaner solution but one that required a platform migration most European capitals have resisted.

The practical consequences for Parisians are modest but cumulative. Residents filing housing assistance claims through the city's En Ligne portal, or tracking Grand Paris Express updates for lines 15, 16, and 17, occasionally encounter image rendering errors or accessibility metadata mismatches that slow load times, particularly on mobile. For the roughly 15 percent of Paris residents who access city services exclusively via smartphone, according to regional digital inclusion surveys, those friction points matter.

The city's working group expects to have the centralised asset library operational by the fourth quarter of 2026, in time to support communication rollouts tied to the Seine-Saint-Denis urban renewal projects feeding off the Olympic legacy programme. Whether the timeline holds is an open question — the same audit that identified the duplicate image problem also found that content upload permissions were spread across more than 300 individual departmental accounts, each requiring renegotiated access protocols before a central library can go live.
