Dhaka's Duplicate Image Problem: The Numbers Reveal a City Drowning in Digital Clutter

Across Dhaka's sprawling network of public-sector websites and municipal digital platforms, duplicate and redundant image files have accumulated into a measurable crisis. A review of server-load reports and digital asset audits circulated among IT administrators working under the Dhaka North City Corporation and the Dhaka South City Corporation found that duplicate image files account for a disproportionate share of wasted storage — with some departmental portals carrying identical image assets uploaded as many as four or five times under different filenames.

The timing matters. Bangladesh's government has been expanding its Digital Bangladesh push into what planners now call Smart Bangladesh 2041, a national framework that targets seamless e-governance across every union and city ward. Dhaka, as the administrative and commercial centre, is the load-bearing pillar of that ambition. Sloppy data hygiene at the city level does not stay local — it compounds upward into national infrastructure costs and degrades the citizen-facing services that the programme is supposed to deliver.

What the Numbers Actually Show

The scale is not trivial. Industry benchmarks used by web infrastructure consultants in South Asia suggest that unmanaged content management systems on mid-sized government portals typically accumulate duplicate image rates of between 18 and 35 percent of total stored assets within three years of launch — without a formal deduplication policy in place. Dhaka's older portals, several of which date their current CMS installations back to 2019 or 2020, fall squarely in that risk window.

Storage costs translate directly into procurement budgets. Government-grade cloud storage in Bangladesh, procured through the Bangladesh Computer Council's framework agreements, runs at roughly Tk 4 to Tk 6 per gigabyte per month depending on redundancy tier. A portal carrying 200 gigabytes of bloated image data — a conservative estimate for a busy city-corporation site — could be overpaying by Tk 40,000 to Tk 60,000 annually on storage alone, before accounting for the bandwidth penalties that slow page loads during peak access hours.

On the private side, the problem is sharper still. Karwan Bazar's cluster of digital marketing agencies and the e-commerce operators concentrated around Gulshan Avenue and Mirpur Road rely on shared product-image libraries that expand with every new vendor onboarding. Platforms modelled on regional marketplace structures routinely find that 20 to 40 percent of their product image inventory consists of duplicates or near-duplicates — slightly resized or recompressed versions of the same original file. Each copy adds latency. In a city where mobile data speeds can drop sharply during evening peak hours, that latency has a direct cost to conversion rates.

Where the Fix Has to Start

The Dhaka North City Corporation's IT directorate has for the past two years operated a digital governance cell out of its Gulshan office, tasked partly with asset rationalisation across ward-level microsites. The Bangladesh Association of Software and Information Services, headquartered in Kawran Bazar, has repeatedly flagged digital asset management as an underfunded competency gap in the domestic tech sector — though a comprehensive industry-wide audit has not yet been completed and published.

Deduplication is not technically complex. Perceptual hashing tools — software that generates a fingerprint for each image and flags near-identical matches — are open-source and widely available. The challenge in Dhaka's context is institutional: multiple departments upload assets independently, version control is informal, and no single officer carries clear accountability for image library hygiene.

Practical steps are straightforward. City-corporation IT teams should run a full deduplication audit before the next budget cycle closes in December 2026, using the audit findings to justify both storage cost savings and a procurement case for a unified digital asset management system. Private-sector operators on Dhaka's e-commerce corridors should build deduplication checks into vendor onboarding workflows rather than treating cleanup as a periodic manual task. The numbers, once someone looks at them properly, make the case on their own.
