How Hong Kong's Duplicate Image Problem Built Up — and Why It's Now Forcing a Reckoning

Hong Kong's digital publishers and government information offices are sitting on a growing problem: thousands of duplicate images lodged inside content management systems, public databases, and archival repositories that have never been properly reconciled. The issue has moved from an irritant to an operational liability, costing storage, distorting search results, and — in several documented cases involving the Hong Kong Government News service on Harcourt Road — surfacing the wrong photograph alongside official press releases.

The reckoning has been building since at least 2019, when the social unrest that preceded the National Security Law triggered an unprecedented surge in news photography. Outlets from the South China Morning Post to now-shuttered titles like Apple Daily were ingesting thousands of frames per week. Archiving standards varied wildly. When some of those titles closed between 2021 and 2022 and their digital assets were partially absorbed by other organisations or migrated to cold storage, duplicate image files — often at different resolutions or with conflicting metadata — entered new systems without deduplication checks.

A Problem Years in the Making

The structural cause is straightforward. Hong Kong's media market compressed dramatically in a short period. Between 2020 and 2023, at least four major Cantonese-language digital outlets either shut down or substantially reduced operations. Their photo libraries did not disappear; they were copied, re-uploaded, and in some cases donated to university archives including the Hong Kong Baptist University Library on Waterloo Road in Kowloon Tong. Without standardised IPTC metadata or hash-based deduplication — tools widely used by wire agencies — those transfers compounded the redundancy problem rather than solving it.

Government digitisation efforts ran into similar trouble. The Government Records Service, which operates under the Government Secretariat and maintains physical and digital holdings across facilities including a depot in Kwun Tong, expanded its digital intake scope after 2021. Officials processed a backlog of departmental photograph collections, many of which had already been partially scanned by individual bureaus. The result was duplicate entries across separate accession numbers — different file names, identical content.

Commercial pressures compounded the technical failures. Cloud storage costs on services used by Hong Kong newsrooms dropped significantly through the early 2020s, removing a financial incentive to prune files. At the same time, search engine optimisation requirements pushed publishers to upload multiple cropped versions of the same image to satisfy different aspect ratios across desktop, mobile, and social channels. By 2024, industry estimates circulating among Hong Kong digital editors suggested that some mid-sized publishers were carrying duplicate-rate ratios — the proportion of stored image files that are near-identical copies of another file in the same system — of between 30 and 45 percent, though those figures have not been independently audited.

Why It Matters More Now

The issue gained sharper attention in the first half of 2026 for two reasons. First, the Hong Kong Communications Authority began consulting on updated digital content standards for licensed broadcasters and online news operators, a process that implicitly requires publishers to demonstrate asset management competence. Second, the broader push for Greater Bay Area data integration — connecting Hong Kong's information infrastructure more directly with counterparts in Shenzhen and Guangzhou — has made clean, non-redundant metadata a practical prerequisite rather than a bureaucratic nicety.

For newsrooms still operating out of offices in Causeway Bay, Wan Chai, and Sai Ying Pun, the practical steps are not technically exotic. Perceptual hashing tools can flag near-duplicate images at scale. Metadata audits, even manual ones, resolve a significant proportion of conflicts. The harder problem is institutional: agreeing on who owns the master copy when an image has been duplicated across two organisations, and whether historical files with stripped or incorrect metadata can ever be reliably attributed.

Publishers and archivists who want to get ahead of any forthcoming regulatory standard would do well to begin deduplication audits now, prioritising collections ingested during the 2019–2022 period when intake volumes were highest and quality controls were weakest. The window to fix this quietly, before compliance becomes compulsory, is narrowing.
