New York Is Racing to Purge Duplicate Images From Its Digital Infrastructure — Other World Cities Are Already Ahead

The city's digital housekeeping bill is coming due. With an estimated 4.7 million unique visitors expected to pass through New York during the 2026 FIFA World Cup group-stage matches at MetLife Stadium in East Rutherford, agencies from the MTA to NYC311 have quietly accelerated efforts to eliminate duplicate images and redundant media files from their public-facing platforms — a problem that has slowed load times on subway digital screens, confused tourists on the NYC Ferry app, and inflated storage costs across multiple municipal data centers.

The timing matters. New York is simultaneously rolling out the final phases of its congestion pricing implementation, expanding MTA digital wayfinding screens across 35 stations on the A, C, and E lines, and trying to present a coherent digital face to international visitors who arrive expecting the seamless experience they got in Paris during the 2024 Olympics or in Qatar in 2022. Duplicate images — the same photograph or graphic stored under multiple filenames across disconnected content management systems — are not glamorous, but city technology officers say they directly affect how fast information loads on public kiosks and apps when network demand spikes.

NYC's Department of Information Technology and Telecommunications, known as DoITT, has been running a deduplication audit across city-managed content systems since January 2026, according to publicly posted procurement records on the city's PASSPort contracting portal. The effort covers assets used by NYC.gov, the MTA's real-time customer information platforms, and the 311 service portal, which logged more than 3.1 million service requests in 2025 alone. The audit is being conducted in partnership with Axon Networks, a Brooklyn-based digital infrastructure firm that won a contract through the city's competitive vendor process. A secondary effort is underway at the Metropolitan Transportation Authority's Communications and Customer Experience division, which manages the countdown clocks and digital maps at Penn Station and Grand Central Terminal.

How New York Compares to London, Tokyo, and Amsterdam

Other major cities hosting large-scale international events have tackled this problem earlier and more aggressively. Transport for London completed a full media asset deduplication across its Journey Planner and TfL Go platforms ahead of the 2022 Commonwealth Games broadcast partnership, reducing redundant image files by roughly 40 percent, according to a TfL digital infrastructure report published that year. Tokyo's Bureau of Digital Services consolidated its multilingual wayfinding image libraries before the 2021 Olympics, centralizing assets under a single content delivery network managed through the city's GovTech arm. Amsterdam's municipal government adopted a unified digital asset management policy in 2023, mandating that all city-affiliated websites and apps draw from a single image repository maintained by the city's CIO office.

New York has no equivalent single-repository mandate yet. Each agency still maintains its own content management system, meaning the same photograph of, say, Times Square or the Fulton Center can exist in dozens of slightly different versions across agency servers — different crops, different compression levels, different filenames — none of which a basic deduplication script will catch automatically. The DoITT audit is attempting to address this with a hash-matching protocol, but the work is manual-intensive and the January-to-June phase covered only about 60 percent of priority systems, based on the PASSPort contract milestone documentation.

What Comes Next for Riders and Visitors

For everyday New Yorkers, the practical payoff is faster load times on the MTA app and more reliable image display on the 472 digital information screens the authority has installed since 2023. For World Cup visitors navigating from Midtown to MetLife via NJ Transit connections at Moynihan Train Hall, a cleaner backend means fewer broken image icons and more consistent multilingual signage on the city's digital kiosks, 14 of which were newly installed along the 34th Street corridor in March 2026.

DoITT's current contract runs through December 2026. If the audit yields the storage savings the agency projects, officials are expected to propose a permanent centralized digital asset management system in the fiscal year 2028 budget cycle — the same timeline Amsterdam used after its own initial audit phase. The full proposal would require City Council approval. Until then, agencies are working from a shared style guide issued in April 2026, which at least standardizes image dimensions and naming conventions going forward, even if the legacy duplicates remain a work in progress.
