Zurich Leads on Duplicate Image Replacement — But Other Cities Are Catching Up Fast

Zurich's city communications office has been quietly overhauling how public-facing digital platforms handle duplicate imagery, replacing generic stock photos with original, locally shot material across municipal websites since a policy revision that took effect in January 2026. The move puts Zurich ahead of several comparable European cities but well behind Amsterdam and Copenhagen, which began systematic duplicate-image audits of their civic portals as early as 2023.

The issue matters more than it might sound. When residents in Wiedikon or Altstetten look up housing information, transit updates or public health resources on the city's digital portals, they increasingly expect to see streets and faces they recognise — not watermarked composites of unnamed European cityscapes repurposed from commercial libraries. Urban communication researchers have linked heavy reliance on stock-image repetition to measurable drops in civic trust, particularly among younger residents who identify visual authenticity as a marker of institutional credibility. Zurich's housing shortage, the so-called Wohnungsnot crisis, has pushed the city's communications load considerably higher over the past two years, making accurate, context-specific imagery more operationally relevant than ever.

What Zurich Is Actually Doing

The practical work falls largely to Stadtentwicklung Zürich, the city's urban development unit, working alongside the media team at Statistik Stadt Zürich on Napfgasse. Starting with the city's housing and planning subpages in the first quarter of 2026, the programme calls for every page flagged as containing a duplicate image — identified through a hash-matching audit tool — to receive a replacement photograph taken within Zurich's twelve districts. Priority was given to pages covering Kreis 4 and Kreis 5, both of which see disproportionately high traffic from renters seeking affordable housing. ETH Zurich's Chair of Information Architecture contributed a methodology paper to the process in late 2025, laying out a reproducible framework for municipalities to detect and categorise visual redundancy across large content management systems.

The canton's digital infrastructure team set a target of clearing 80 percent of flagged duplicates by the end of the third quarter of 2026 — a figure cited in the city's digital strategy update published on zurich.ch in March 2026. Each original photograph commissioned under the programme costs the city between CHF 180 and CHF 350, depending on usage rights, compared to the CHF 12 to CHF 40 per image that stock licensing had previously cost annually. The higher unit cost is offset, the strategy document argues, by eliminating recurring licence renewals and reducing legal exposure from image rights disputes.

How Other Cities Compare

Amsterdam completed a full duplicate-image sweep of its gemeente.amsterdam.nl portal in 2024, replacing roughly 4,200 flagged images over eighteen months. Copenhagen took a different approach: rather than a centralised audit, it embedded image-duplication checks directly into its content management system, so editors are flagged at the point of upload. Vienna, whose municipal web estate is broadly comparable in scale to Zurich's, has not yet published a formal policy on the issue, though its communications directorate acknowledged the matter in a published annual report for 2025.

London's situation illustrates the challenge of scale. The Greater London Authority has thirty-three boroughs each managing their own digital content, and standardising image practices across that structure remains unresolved as of mid-2026. Berlin, which overhauled its berlin.de portal after a widely reported image licensing dispute in 2024, has moved to an open-licence-first policy rather than focusing explicitly on duplicate reduction — a different priority that nevertheless produces a similar effect.

For Zurich residents, the practical upshot is straightforward: check the city's housing and planning pages from the third quarter of 2026 onward for updated, locally specific visuals. For content managers at cantonal and federal agencies that have not yet conducted image audits, ETH Zurich's January 2026 methodology paper is publicly available through the university's research repository and offers a documented starting point that requires no specialist procurement.
