Wollongong's duplicate image problem: the numbers exposing a hidden drain on local business websites

At least one in three small business websites audited by Wollongong-based digital agency Coastal Web Co in the first half of 2026 contained duplicate images — the same photo file uploaded multiple times under different filenames, bloating page sizes and quietly punishing the businesses in Google's search algorithm. The agency's internal audit, covering 140 local sites between January and June, found the problem was most common in hospitality, trades, and retail — sectors that dominate the Crown Street Mall precinct and the Keira Street corridor.

The timing matters. With the Illawarra Shoalhaven Regional Development Fund directing investment toward small business digitalisation, and the University of Wollongong's Smart Region Incubator pushing local operators to sharpen their online presence, duplicated and unoptimised image libraries represent a measurable drag on that investment. A site carrying redundant image files can be two to four times heavier than it needs to be — and page load speed is a confirmed ranking factor in Google Search as of its 2021 Core Web Vitals update, which remains embedded in its algorithm today.

What the data actually shows

The numbers get specific quickly. Google's own benchmark data, published via its PageSpeed Insights tool, flags anything above a 2.5-second Largest Contentful Paint score as needing improvement. Sites with duplicate image libraries routinely score above four seconds on mobile — the device most Wollongong users reach for first. Mobile accounts for roughly 60 percent of web traffic across Australian retail categories, according to the Australian Bureau of Statistics' 2024-25 digital economy survey.

Image duplication typically happens in one of three ways: a content management system like WordPress creates multiple resized versions of each uploaded file without deleting the originals; staff upload the same product or venue photo from different devices across different months; or website migrations from one platform to another copy entire media libraries wholesale, doubling or tripling stored files. A single hospitality venue in the Wollongong CBD — the kind operating a 40-table restaurant with a regularly updated menu gallery — can accumulate more than 800 image files when the functional requirement is closer to 200.

Storage is cheap, but performance penalties are not. Hosting providers that charge a flat fee up to a set storage threshold — common at around 10GB for entry-level business plans — begin levying overage charges or forcing plan upgrades when bloated media libraries push sites past that ceiling. At current rates from major Australian providers, that upgrade typically costs an extra $15 to $30 per month. Across twelve months, a Port Kembla fabrication supplier or a Thirroul café owner is paying $180 to $360 annually for a problem that a systematic image audit could eliminate in an afternoon.

What local operators can do before year's end

The remediation process is more straightforward than business owners tend to assume. Free tools including Google Search Console and the open-source plugin Imagify can identify duplicate and oversized image files within minutes of installation on a WordPress site. The University of Wollongong's Smart Region Incubator runs quarterly digital health workshops — the next is scheduled for August 2026 at Innovation Campus on Squires Way, North Wollongong — where participants receive a structured website audit covering exactly these issues.

For businesses not yet connected to that program, the practical first step is running Google's PageSpeed Insights report on the homepage and any gallery or product pages. A score below 50 on mobile is a red flag warranting closer investigation. The audit itself costs nothing. Fixing what it finds usually costs a few hours of someone's time, or a one-off fee to a local developer — a significantly smaller number than a year of unnecessary hosting upgrades or the cumulative cost of ranking below a competitor whose site simply loads faster.

The Illawarra's digital economy ambitions — from Port Kembla's energy transition communications to the university's research commercialisation pipeline — depend partly on whether local businesses can present themselves credibly online. Duplicate images are a mundane problem. The data says it is also a widespread one.
