Milan's War on Duplicate Images: How the City Stacks Up Against London, Paris and New York

Milan's civic digital office confirmed this spring that the city's public-facing image database — used by municipal agencies, tourism platforms and event promoters tied to the Milan-Cortina 2026 Winter Olympics — contained an estimated 34 percent rate of duplicate imagery across its asset library, a figure that administrators say has forced an overhaul of how the city licenses, tags and circulates visual content.

The problem is not cosmetic. For a city whose global identity is inseparable from its visual brand — the fashion weeks, the Salone del Mobile, the Galleria Vittorio Emanuele II — repeated images dilute the distinctiveness that advertisers and cultural institutions pay a premium to access. With the Winter Olympics opening ceremony scheduled for February 6, 2026, in Cortina d'Ampezzo, the pressure on Milan's image management infrastructure arrived earlier than anyone anticipated.

What Milan Is Actually Doing About It

The city's approach centres on two initiatives. The first is a procurement contract awarded to a Milan-based tech consortium operating out of the Porta Nuova innovation corridor, tasked with deploying perceptual hash detection across the Comune di Milano's digital asset management system. Perceptual hashing identifies images that are visually near-identical even when file names, metadata or compression levels differ — a smarter filter than simple duplicate-file checks.

The second initiative involves the Brera Academy of Fine Arts, which signed a memorandum of understanding with the Comune in March 2026 to develop ethical guidelines for AI-generated image use in civic communications. The concern: AI tools flooding city campaigns with algorithmically recycled visuals that are technically unique files but functionally indistinguishable from one another, a new category of duplication that older software cannot catch.

Compared with peer cities, Milan is moving at a pace that specialists describe as mid-table. London's Government Digital Service published its image deduplication framework for public-sector use in January 2025, covering 47 national and municipal agencies. Paris, through its Direction de la Communication de la Ville de Paris, began mandatory deduplication audits for all city-funded cultural events in September 2024 — a requirement now embedded in grant agreements worth up to €80,000 per recipient organisation. New York City's Department of Cultural Affairs rolled out a centralised media asset platform called NYC Cultural Commons in late 2024, consolidating imagery from more than 1,100 funded organisations.

Why the Stakes Are Higher Here

Milan's fashion and design economy gives image duplication a financial dimension that most cities do not face at the same intensity. A single photograph of the Via Montenapoleone shopping strip, licensed incorrectly or circulated as a duplicate across competing luxury brand campaigns, can trigger contractual disputes between brands — several of which maintain flagship stores within 200 metres of each other along that four-block stretch.

The Camera Nazionale della Moda Italiana, which coordinates fashion week logistics from its offices near Piazza della Repubblica, has separately begun requiring member brands to submit unique image declarations before receiving official event accreditation. That requirement, introduced for the February 2026 fashion week cycle, represents an industry-side push that complements rather than duplicates the city's civic effort.

The Lombardy regional government, whose relationship with the centre-left Sala administration at Palazzo Marino has been tense on multiple policy fronts, has not formally engaged with the city's image deduplication programme. Regional communications funds remain administered separately, creating an awkward gap in the overall framework — particularly for venues like the Fiera Milano exhibition complex in Rho, which straddles city and regional jurisdictions.

Practically, what changes for Milanese institutions and businesses is straightforward: organisations applying for city co-funding on events connected to the Olympics or to Milan's broader 2026 cultural calendar should expect image audits as part of their application documentation. The Comune's digital office has indicated the audit tool will be available to non-profit cultural groups at no charge from September 2026. Commercial operators, including agencies and publishers working in the fashion and design sector, will be directed toward the consortium in Porta Nuova for paid licensing and compliance checks. Getting ahead of the requirement now, rather than scrambling during the Olympic window, is the cleaner path.
