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

Milan has a duplicate image problem. The city's municipal communications office, the Comune di Milano, confirmed in a June 2026 internal review that roughly 34 percent of assets held across its official digital platforms were flagged as redundant copies — photographs, renderings and promotional stills that had been uploaded multiple times across different departments, often with conflicting metadata. The review, covering assets accumulated since 2019, prompted a formal remediation project launched this past spring.

The timing matters. With the Milan-Cortina 2026 Winter Olympics now less than six months from their February opening ceremonies, the pressure to present a clean, consistent visual identity to a global audience has become acute. Duplicated or mismatched imagery in official communications is not a trivial housekeeping issue — it creates legal exposure around image rights, confuses international press desks and undermines the coherent city brand that Milan's fashion and design economy depends on year-round.

What Milan Is Actually Doing

The practical work is happening at two levels. The Triennale di Milano, whose permanent archive spans design documentation going back to the institution's 1933 founding, began a perceptual-hash deduplication project in March 2026, partnering with a Florence-based digital-preservation firm to process an estimated 280,000 image files. Perceptual hashing compares images visually rather than file-by-file, catching near-duplicates — a rescaled JPEG of the same architectural photograph, for instance — that a simple checksum would miss.

Separately, the Porta Nuova district's commercial property consortium, which manages advertising and promotional rights across the Piazza Gae Aulenti development and surrounding towers, updated its content licensing rules in April 2026. The new protocol requires any agency or brand buying outdoor digital display space to submit imagery through a single asset-management portal that cross-checks uploads against a master catalogue. The goal is to eliminate the recurring problem of the same campaign visual appearing simultaneously in incompatible colour-calibrated versions across different LED surfaces in the same block.

Both initiatives reflect a broader shift inside Italian institutions toward treating image data the way finance departments treat transaction records — with reconciliation processes and audit trails.

How Milan Compares to London, Paris and New York

The comparison cities are instructive. Transport for London overhauled its asset-management infrastructure in 2023, centralising more than 1.2 million media files under a single digital-asset-management system following a Freedom of Information disclosure that revealed dozens of licensed photographs had been used past their contractual expiry dates across TfL's publicity materials. Paris's city administration consolidated its image libraries ahead of the 2024 Olympics, reportedly reducing internal storage costs by cutting duplicate file counts by more than 40 percent, according to reporting by Le Monde at the time. New York City's Department of Cultural Affairs has operated a unified image-rights database since 2021, mandatory for all institutions receiving city funding above a threshold of $500,000 annually.

Milan is arriving at this discipline later than London or Paris, partly because the city's cultural institutions have historically operated with a high degree of autonomy. The Pinacoteca di Brera and the Museo del Novecento, both on the central Via Brera and Piazza del Duomo axes respectively, each maintain separate digital archives with no formal cross-institutional deduplication agreement in place as of this month. That gap is increasingly visible to international curators and rights agencies who work across multiple Milan institutions simultaneously.

The cost differential is not trivial. Cloud storage for large image archives runs, at current market rates, between €0.02 and €0.04 per gigabyte per month on major European platforms. For institutions holding tens of terabytes of redundant files, the annual waste can reach five figures before factoring in staff time spent managing conflicting versions.

For anyone dealing with Milan's institutions practically — whether a foreign press photographer licensing work, a brand agency buying Porta Nuova display space, or a researcher accessing Triennale archives — the immediate advice is the same: submit a rights query through each institution's official asset portal before assuming an image is freely available. The deduplication projects underway will eventually surface which copies carry the correct rights metadata and which do not, but that process will not be complete until at least early 2027. Until then, the administrative picture in Milan remains messier than in London or Paris, and verification before use is essential.
