Duplicate Image Replacement: What Officials, Experts and Key Figures Are Saying

Duplicate images are clogging the digital infrastructure of Wollongong-area organisations — and the question of who is responsible for fixing the problem, and how, is drawing sharply different answers from council administrators, university researchers and local business operators.

The issue came into sharper focus this week as institutions across the Illawarra region reviewed their content management systems ahead of a July 31 compliance deadline tied to state government accessibility standards for public-sector websites. Duplicate imagery — where the same photograph or graphic asset appears multiple times under different file names — creates problems ranging from slower page-load times to screen-reader failures that affect users with vision impairment.

Wollongong City Council confirmed it is currently auditing digital assets across its online platforms. The audit covers council's main website, the Wollongong City Library digital catalogue portal and community notice boards linked to neighbourhood centres in Figtree and Fairy Meadow. Council has not publicly released figures on the volume of duplicates identified, but a council spokesperson confirmed the review is underway and tied to the NSW Government's updated Web Content Accessibility Guidelines obligations.

Universities and Industry Weigh In

At the University of Wollongong on Northfields Avenue, the Faculty of Engineering and Information Sciences has been examining duplicate-image problems from a technical rather than compliance angle. Researchers there working on automated deduplication pipelines — tools that scan repositories and flag redundant files for review — say the challenge is not simply identifying copies, but determining which version of an image is the authoritative one to keep. That distinction matters enormously when images are tied to legal, heritage or scientific records.

Local digital agency operators along Crown Street in the CBD say clients frequently underestimate the downstream cost of unmanaged image libraries. One commonly cited industry benchmark puts the time cost of manually reviewing and replacing duplicate assets in a mid-sized website at between 40 and 80 hours for a library of around 5,000 images — a figure that translates to significant contractor fees at current Wollongong market rates for web development work.

The conversation also touches BlueScope Steel's Port Kembla operations, where the company's internal communications and engineering documentation systems run extensive image libraries tied to safety manuals and process diagrams. Industry observers note that in highly regulated manufacturing environments, a duplicate image appearing in the wrong document version is not a cosmetic problem — it can create genuine compliance risk. BlueScope has not made a public statement on its internal image management practices.

What the Practical Pathway Looks Like

The emerging consensus among practitioners — drawn from public forums and published guidance rather than any single organisation's position — is that replacement of duplicate images should follow a three-stage process: automated detection using hash-comparison tools, human editorial review to confirm canonical versions, and a documented redirect or replacement log that can be audited later.

For Wollongong's creative and media businesses, several of which cluster around the Wollongong Innovation Campus on Squires Way in North Wollongong, the stakes are partly commercial. Stock photography libraries used in client campaigns routinely accumulate duplicates as teams across different departments download the same asset independently. By some industry estimates, storage costs for unmanaged media libraries in small-to-medium businesses run 15 to 20 percent higher than they would with active deduplication policies in place.

The July 31 accessibility deadline is the immediate pressure point for public-sector bodies. For private operators and the university sector, the motivation is more likely efficiency and risk management than regulatory compliance — though those two things are converging as digital governance standards tighten at both state and federal levels.

Organisations yet to begin a duplicate-image audit should, according to publicly available NSW Digital Government guidance updated in March 2026, prioritise any images embedded in forms, instructional pages or emergency information first, since those carry the heaviest accessibility obligations and the greatest risk if displayed incorrectly or replaced with the wrong version.
