Duplicate Images Online: What Officials, Experts and Key Figures Are Saying

Digital asset managers, archivists and communications professionals across Melbourne are raising fresh concerns about a problem that has quietly compounded for years inside government departments, cultural institutions and private businesses: duplicate images cluttering digital libraries, inflating storage costs and, in some cases, creating legal exposure around licensing and attribution.

The issue has sharpened in 2026 as several Victorian public bodies have begun auditing their digital holdings ahead of a broader data-governance push tied to the state government's Digital Strategy refresh, which the Department of Government Services has flagged for implementation before the end of the financial year. Across the city, the question of what to do once duplicate images are found — replace them, delete them, or simply tag them — is generating real disagreement among those responsible for managing the files.

The Scale of the Problem in Melbourne

The City of Melbourne's digital asset library, which covers everything from council event photography to planning imagery captured across the CBD and inner suburbs, has undergone periodic deduplication reviews, though the specifics of how many duplicate files have been identified in recent audits have not been made public. What is known is that storage costs for large municipal image libraries have risen sharply across Australian local governments in recent years, with cloud storage pricing and licensing fees for image management software both increasing since 2022.

At the State Library of Victoria on Swanston Street, cataloguers have long grappled with duplicate digitised images — the same historical photograph scanned multiple times at different resolutions, entered into the collection database more than once, sometimes under conflicting metadata. Archivists there have discussed the challenge at sector conferences, noting that removing a duplicate is never as simple as deleting a file: provenance records, linked catalogue entries and existing citations all need to be checked first.

Creative agencies and production studios concentrated along Flinders Lane and in Collingwood's Smith Street precinct face a more commercial version of the same headache. When a client's image library contains duplicates, it can mean paying for the same stock licence twice, or worse, using an image whose original licence has expired because the properly licensed version was stored elsewhere and the team went to the duplicate copy by habit.

What Practitioners Are Recommending

Digital asset management specialists working with Melbourne-based organisations generally point to the same sequence: identify, assess, then act. Identification requires software capable of hashing images — comparing files at a pixel level rather than relying on file names — because duplicates are frequently renamed across departments and over time. Assessment means checking whether both (or all) versions of an image carry valid metadata and licensing before anything is deleted. Only then does replacement or consolidation become safe.

The practical advice circulating among practitioners is that a blind deletion policy, without that assessment step, creates its own risk: an organisation could remove the only correctly licensed copy and retain a version with no clear rights provenance. For public bodies in Victoria, that is not a trivial concern given the state's ongoing reforms to public records obligations under the Public Records Act 1973 and its associated standards enforced by the Public Record Office Victoria.

For smaller organisations — community groups in Fitzroy, arts collectives operating out of venues in Northcote, neighbourhood houses across the western suburbs — the practical path is more constrained. Many lack dedicated digital asset management systems at all. Free or low-cost deduplication tools exist, but applying them responsibly still requires someone with enough knowledge to interpret the results and make decisions about what to keep.

The coming months will test whether the state government's digital governance push translates into concrete guidance for agencies on exactly this kind of operational question. Departments have been told to align their asset management practices with updated whole-of-government standards, but the detail of what that means for image libraries specifically — including whether duplicate replacement will be mandated, recommended or left to agency discretion — has not yet been spelled out in any publicly released framework document.
