Delhi's Duplicate Image Problem: How the Capital Stacks Up Against London, Seoul and São Paulo

Delhi's public-facing digital infrastructure — spanning municipal portals, Metro information boards, government scheme websites and civic app interfaces — is carrying a measurable load of duplicate imagery that wastes bandwidth, confuses residents and undermines the credibility of official communications. The problem surfaced as a formal concern in internal reviews conducted by the Delhi government's Information Technology Department in early 2026, when audits of citizen-service platforms found redundant image assets inflating page-load times and cluttering search results across several key portals.

This matters now for a specific reason. Delhi Metro Phase 4, whose new corridors are scheduled to begin partial operations by late 2026, is generating enormous volumes of new wayfinding graphics, promotional banners and safety instruction images for deployment across stations and apps. Without a centralised digital asset management system, agencies risk repeating the same failures that clogged earlier Metro expansions: identical images uploaded under different filenames, conflicting visuals across Hindi and English versions of the same page, and outdated photographs of stations that no longer look as pictured.

What's Happening on the Ground

The issue is visible in places residents use every day. The Delhi Tourism and Transportation Development Corporation's website, which covers routes connecting Old Delhi landmarks including the Red Fort and Jama Masjid to newer south Delhi hubs, has at various points displayed the same promotional photograph of Humayun's Tomb across more than a dozen separate pages — each stored as a unique file, each loading independently. The South Delhi Municipal Corporation's property tax portal, which handles millions of transactions annually, has carried duplicate form-guidance graphics that differ only in compression quality. Neither problem is catastrophic in isolation. Together, across dozens of agencies, they add up.

Civic technology groups tracking these issues point to a structural gap. Delhi lacks a single digital asset registry equivalent to what the Government of the United Kingdom deployed through its GOV.UK platform after 2013, when the Government Digital Service mandated centralised image libraries to eliminate exactly this kind of redundancy. Seoul's Smart City division, operating under the Seoul Digital Foundation, has maintained a unified media repository since 2019 that all 25 autonomous district offices draw from, reducing duplicate public-facing assets by a reported margin that city officials have cited publicly in annual digital governance reports. São Paulo's municipal government launched a similar consolidation effort through its Secretaria Municipal de Inovação e Tecnologia in 2022, specifically targeting image duplication on the Nota Fiscal Paulistana consumer portal.

Delhi's Patch-Work Response

Delhi's current response is fragmented. The Dialogue and Development Commission of Delhi, which advises on urban policy, has flagged digital infrastructure rationalisation in working papers circulated this year. The Delhi e-Governance Society, which manages the Delhi government's cloud infrastructure under the NIC framework, has the technical capability to build a shared asset management layer but has not publicly committed to a timeline for doing so. Meanwhile, individual departments are making ad hoc fixes — the Delhi Jal Board, for instance, updated its Yamuna cleanup campaign page in March 2026, removing several repeated infographic images as part of a broader site refresh tied to the ongoing river remediation programme.

The bandwidth cost is not trivial. A 2024 benchmarking study by the Internet and Mobile Association of India found that poorly optimised government websites — including those burdened with duplicate image files — loaded on average 40 percent slower than private-sector counterparts on 4G connections. For users in areas like Shahdara or Mustafabad where connectivity remains inconsistent, that gap translates directly into abandoned sessions and failed form submissions.

The practical path forward is well understood even if politically unexciting. A centralised image repository, mandatory file-hash checking before any upload to government servers, and a quarterly audit cycle would address the core problem within a single budget cycle. London's Government Digital Service framework and Seoul's district media pool offer ready-made templates. Delhi's IT Department would not need to invent a solution — it would need to borrow one, fund a team to implement it, and enforce compliance across agencies that have historically operated as silos. Phase 4 station launches later this year provide a natural deadline to aim for.
