How Glasgow's Public Image Archive Ended Up Full of Duplicates — and What's Being Done to Fix It

Glasgow City Council's digital image archive contains an estimated 40,000 duplicate or near-duplicate photographs, the result of more than a decade of fragmented record-keeping across at least seven separate departments that were never brought onto a single platform. The problem, long known internally, has only recently become the subject of a formal remediation programme after a 2025 audit flagged the scale of the waste.

The stakes are higher than they might appear. When public-facing bodies — from the Glasgow Life cultural trust to the city's planning directorate — pull images for reports, consultation documents or promotional material, they are drawing from a pool that has never been properly curated. Duplicate images slow retrieval, inflate storage costs, and in several documented cases have led to the wrong photographs being published in planning notices covering areas including Govan, Shawlands and the Merchant City.

How the Problem Accumulated

The roots go back to roughly 2008, when individual council departments began digitising their own photographic records without a shared taxonomy or central server. The Economic Development team, the roads and infrastructure unit, and what was then the Culture and Sport Glasgow body — the predecessor to Glasgow Life, which launched in April 2007 — each built separate folder structures and naming conventions. When Culture and Sport became Glasgow Life in 2011, its image files migrated incompletely, leaving orphaned duplicates on legacy servers that continued to be backed up for years.

A subsequent push to digitise physical planning photographs taken between the 1970s and 1990s — covering major regeneration sites along the Clyde waterfront and in areas such as Partick and Bridgeton — added tens of thousands of new scans without any deduplication check against what already existed digitally. By 2019, the Glasgow City Region City Deal programme was generating its own image bank for infrastructure projects, again without cross-referencing the council's main archive. The result was three overlapping systems, none of them authoritative.

Storage costs have mounted accordingly. Cloud hosting for the council's unstructured digital assets — a category that includes image files — cost the authority approximately £1.2 million in the 2024-25 financial year, according to figures included in the council's published digital transformation strategy from October 2025. Officers have estimated that a properly deduplicated archive could reduce that storage burden by between 25 and 30 percent.

The Current Remediation Effort

Glasgow City Council's Digital Services team began a structured deduplication project in January 2026, working with the council's records management unit based at the Olympia building on Bridgeton's Olympia Street. The programme uses hash-matching software to identify pixel-identical files, followed by manual review of near-duplicates — images taken in the same location within seconds of each other, which may or may not be functionally redundant depending on their metadata.

Glasgow Life, which manages 35 venues across the city including the Kelvingrove Art Gallery and Museum and the Glasgow Royal Concert Hall on Sauchiehall Street, is running a parallel review of its own image holdings. The trust's collections and digital teams are working through an estimated 18,000 event and venue photographs that were ingested from multiple sources between 2011 and 2023 without consistent metadata tagging.

The council has set an internal target of completing the first-pass deduplication across core departments by the end of October 2026. That deadline is tied to a planned migration to a unified digital asset management platform that is part of the broader digital transformation programme approved by the city administration in late 2025. Whether the October date holds will depend partly on staffing levels within the Digital Services team, which has two open positions as of this month.

For residents and journalists who regularly request images through Freedom of Information submissions, the practical advice for now is to be as specific as possible — naming the street, the date range, and the department most likely to hold the original — rather than filing broad requests that currently trawl all three overlapping systems. The council's FOI team, reachable through the City Chambers on George Square, has confirmed it is aware of the retrieval delays caused by duplicate records and is prioritising those requests while the remediation work continues.
