How Hong Kong's Duplicate Image Problem Got This Bad: The Paper Trail Behind a Digital Headache

Hong Kong's public-facing digital infrastructure has a clutter problem. Across government portals, university repositories, and commercial news platforms, the same photographs are stored, indexed, and published multiple times under different file names, metadata tags, and access permissions — costing storage budgets, slowing search results, and, in some cases, creating legal liability around licensing. The issue did not appear overnight.

The roots of what archivists and digital asset managers now call the duplicate image problem stretch back to roughly 2013 and 2014, when newsrooms and public bodies across the city began migrating from print-era filing cabinets to digital content management systems with little coordination and no shared standard. The Immigration Tower on Gloucester Road kept one system. The Hong Kong Public Libraries under the Leisure and Cultural Services Department ran another. Private media groups along Wan Chai's media corridor adopted off-the-shelf platforms that rarely spoke to each other.

A Rush to Digitise, a Failure to Standardise

The pressure to digitise fast came from the top. The Hong Kong government's Digital 21 Strategy, updated in 2014, pushed departments to move records online and improve citizen access. The ambition was real. The coordination was not. Departments uploaded image libraries independently, often scanning physical prints that had already been digitised once before, producing second- and third-generation duplicates with degraded metadata. The problem compounded every time a new content management system replaced an old one, typically on a five-to-seven year procurement cycle, and legacy files were bulk-imported without deduplication.

At the Hong Kong Baptist University Library in Kowloon Tong, archivists began flagging the issue internally as early as 2017, according to documentation reviewed by this newspaper. The City University of Hong Kong's Run Run Shaw Library reported similar cataloguing strain. Neither institution had a mandate to share deduplication protocols across sectors.

The emigration wave that accelerated after 2020 made everything worse. Experienced digital librarians and photo editors — many with institutional memory stretching back fifteen years — left for the United Kingdom and Canada, taking tacit knowledge of where duplicate batches lived inside legacy folders. Replacements were hired, but onboarding them into half-documented systems meant new uploads often skipped the manual checks that had previously caught redundant files.

The Numbers That Finally Forced Action

A 2025 internal audit by one government-linked statutory body — details of which were shared with this newspaper without identifying the originating department — found that approximately 34 percent of images stored across its primary and backup servers were duplicates consuming an estimated HK$2.1 million in annual cloud storage costs alone. That figure does not include the staff hours required to manually sort results when search queries return the same photograph twelve times with twelve different file names.

Commercial pressures told a similar story. The shift toward Greater Bay Area content partnerships after 2021, under the framework promoted by the Innovation and Technology Bureau, brought a fresh wave of image imports from Mainland-based partners operating on entirely separate digital asset systems. File naming conventions differed. Colour profiles differed. Rights clearances were documented differently. The result was another layer of duplication stacked on top of the existing mess.

Industry bodies, including the Hong Kong Press Photographers Association based in Sheung Wan, have been pushing since late 2024 for a city-wide image metadata standard that could be adopted voluntarily across newsrooms, libraries, and government departments. Progress has been slow. A working group convened by the HKPPA met three times between January and April 2026 but has not yet published recommendations.

For institutions and newsrooms looking to get ahead of the problem now, digital asset managers recommend starting with hash-based deduplication tools — software that compares actual pixel data rather than file names — before attempting any manual review. The Library Services Centre on Tsuen Wan's Texaco Road ran a pilot of one such tool in early 2026 and reduced its active image library by roughly 22 percent within six weeks. The broader fix, however, will require the kind of cross-sector coordination that has eluded Hong Kong for the better part of a decade. The working group's next scheduled meeting is September 2026.
