'My grandmother's face was replaced by a stranger': Chicago residents speak out on duplicate image replacement

A Logan Square mother opened her daughter's school portal in late June and found a stock photo of a different child where her daughter's profile picture should have been. A Pilsen muralist discovered that a digital archive managed by a city-affiliated arts nonprofit had replaced his original photograph with a generic image pulled from an online library. A retired postal worker in Chatham found his late wife's face missing from a digitised community history project — replaced, without explanation, by a placeholder.

These are not isolated glitches. Across multiple Chicago neighbourhoods, residents are raising alarms about a practice they are calling duplicate image replacement — the automated or manual swapping of personal, community, or culturally significant photographs with substitute images in databases, apps, and public-facing digital platforms.

The complaints have been escalating through the summer of 2026, with community members filing grievances to the Chicago Commission on Human Relations and reaching out to advocacy organisations including the Invisible Institute, the South Side–based journalism nonprofit that has tracked civic data misuse for years.

Who Gets Replaced?

The people raising the loudest objections tend to come from the same zip codes that have historically had the least say over how their data is managed. In Englewood, members of a neighbourhood association say photographs submitted for a 2024 city-sponsored mural registry — a program under the Chicago Department of Cultural Affairs and Special Events — were later found replaced with stock imagery when the registry moved to a new content management system. In Bronzeville, a community memory archive tied to the Harold Washington Cultural Center lost dozens of resident-submitted photographs during a platform migration earlier this year, with substitute images inserted in their place.

Residents say the harm is not abstract. When a grandmother's photograph is replaced by a stock image of an anonymous elderly woman, families lose something real. When a muralist's face disappears from a database and a generic avatar takes its place, so does his authorship. The effect, many say, is erasure — the digital equivalent of redlining a person out of their own neighbourhood's record.

The Invisible Institute, which operates out of offices on South Michigan Avenue and has documented civil rights violations in Chicago since 2013, has begun fielding formal complaints from affected residents. Staff there have been connecting complainants with digital rights attorneys and advising people on how to submit records requests under the Illinois Freedom of Information Act.

The Mechanics — and the Accountability Gap

The technical cause behind most of these replacements appears to be automated deduplication software — tools designed to purge duplicate files from large databases. When two photographs share similar metadata, file size, or pixel signatures, the software may delete one and substitute another, often without logging which image was removed or why. The problem compounds when a platform vendor changes mid-contract, as happened when the city moved several cultural databases to a new hosting arrangement in early 2026.

Chicago's municipal technology infrastructure covers more than 600 active databases, according to the city's own data portal documentation. Oversight of what happens to images and personal files during migrations falls across multiple departments, and residents say there is no single office they can call to report a problem.

State Representative Theresa Mah's 2nd District office on the North Side has received a handful of constituent inquiries on the issue, according to a staffer who spoke generally about the volume of technology-related complaints coming in this year. No city ordinance currently requires vendors to notify residents when their images are altered or replaced in a city-affiliated system.

For now, residents have a few practical options. Filing a FOIA request with the specific department that manages the database in question is the most direct route to documentation. The Chicago Digital Equity Council, which holds public meetings monthly at the Chicago Public Library's Harold Washington branch on South State Street, has offered to help residents navigate the complaint process. Anyone who submitted photographs to a city-affiliated program and suspects their image has been replaced can also contact the Illinois Attorney General's privacy office, which began accepting digital identity complaints in January 2025. The harder question — who audits the auditors — has no clean answer yet.
