'My Grandmother's Face Is Gone': Prague Residents Speak Out on the Surge of Duplicate Images Erasing Family History

Dozens of Prague residents have come forward in recent weeks to report a troubling phenomenon: personal and community photographs submitted to city-run digital portals have been replaced by visually similar but incorrect duplicate images, stripping away authentic local and family records. The complaints, which began surfacing in earnest around May 2026, now span neighbourhoods from Žižkov to Smíchov, and have drawn the attention of Prague City Hall's Department of Digital Services.

The issue matters now because Prague has spent the past three years digitising its civic memory. The city's flagship Praha Digital 2024–2027 programme, administered through the Municipal House on náměstí Republiky, encouraged residents to upload historical photographs and neighbourhood documentation to a centralised archive. That effort has value — but it also created a single point of failure when automated deduplication software began flagging and replacing images it deemed redundant.

From Vinohrady to Holešovice: The Human Cost of an Algorithm

The consequences are not abstract. Residents of Mánesova Street in Vinohrady described submitting scanned family photographs from the 1960s, only to find them replaced weeks later by generic stock images of Prague streetscapes. A ceramics collective operating out of a workshop near Holešovice market, Tržnice Holešovice, said three years of documentation of their public art installations had been overwritten by duplicate images pulled from a commercial image library. The collective has been working with the Prague 7 district office since June to recover the originals, without resolution as of this week.

Community members have also flagged problems with social media platforms themselves. The Žižkov-based community group Sousedé Žižkova, which maintains a Facebook archive of local street art and neighbourhood events, reported that Facebook's automated image-matching system removed 47 of their uploaded photographs between March and June 2026, replacing previews with unrelated duplicates from other accounts. The group estimates at least a third of those images are unrecoverable from their own storage.

The Prague Cultural Heritage Foundation, based on Valdštejnské náměstí in Malá Strana, has been fielding calls from affected residents since April. The foundation documented more than 120 individual complaints by the end of June. That number, foundation staff confirmed in a public notice posted to their website on 30 June, does not include reports made directly to district offices or platform companies.

What Residents Are Being Told to Do — and What Actually Works

Prague City Hall issued a guidance note on 18 June advising residents to retain offline backups of any images submitted to city portals, and to use the official image dispute form available through the Portál Pražana platform. The form, introduced as part of the Praha Digital programme, allows residents to flag incorrect replacements and request manual review. City Hall said reviews are currently taking between 14 and 21 working days.

That timeline frustrates many. Families preparing commemorative events or exhibitions cannot wait three weeks for a bureaucratic process to confirm what they already know: their photographs have been swapped out by software that cannot distinguish a grandmother's face from a stock image of Charles Bridge.

The Prague 3 district office, which covers Žižkov and Vinohrady, has separately opened a walk-in advice session every Tuesday at its offices on Havlíčkovo náměstí, where residents can bring storage drives and printed originals to lodge complaints in person. District staff said the sessions have been consistently full since they launched on 9 June.

For residents whose images are gone entirely, the foundation on Valdštejnské náměstí is coordinating with the National Film Archive and the Municipal Library of Prague on Mariánské náměstí to cross-reference donated collections. It is slow, painstaking work, and there is no guarantee of success.

The practical advice right now is straightforward: audit any images you have submitted to city digital platforms before the end of July, download originals from your own devices before they are overwritten locally, and file a dispute through Portál Pražana if replacements have already appeared. The problem is not going away quickly. The Praha Digital programme's deduplication software is under review, but no suspension has been announced.
