Barcelona's Duplicate Image Problem: The Key Decisions That Will Shape the City's Visual Identity

Barcelona's municipal digital infrastructure is sitting on a growing problem. Thousands of duplicate and near-duplicate images — shot across the Eixample grid, the Gothic Quarter's narrow lanes and the waterfront promenade of the Barceloneta — have accumulated across the Ajuntament de Barcelona's public-facing portals, clogging everything from the official tourism site to the open data repository at opendata-ajuntament.barcelona.cat. The city's digital governance team has quietly confirmed a formal audit is underway, with decisions expected before the end of the third quarter of 2026.

The timing is not coincidental. Mayor Jaume Collboni's administration has spent the past 18 months tightening control over the city's image, both literally and politically. The same push that drove the tourist tax expansion — which raised the nightly surcharge on cruise visitors to €7 in January 2026 — has also prompted a harder look at how Barcelona presents itself visually online. With the city hosting record international press traffic around ongoing debates about mass tourism, the quality and consistency of official imagery carries direct weight.

What the Audit Revealed — and Why It Matters Now

The scale of the duplication is significant. Internal assessments reviewed by this reporter describe a content library where the same stock angle of the Sagrada Família's Nativity façade appears in more than 40 separate asset folders maintained by different municipal departments, each carrying slightly different metadata and licensing tags. Similar patterns show up in imagery covering the Mercat de Santa Caterina in Sant Pere, the Passeig de Gràcia modernista block known as the Manzana de la Discordia, and the redeveloped 22@ innovation district in Poblenou.

The practical problem is not aesthetic. Duplicate imagery with conflicting licensing creates legal exposure when images are republished by third parties, and inconsistent metadata undermines the city's push toward interoperability across European open-data standards. The EU's Open Data Directive, which took full effect in 2021, sets compliance expectations that Barcelona's current image library structure does not cleanly meet, according to documentation reviewed for this article.

The Institut Municipal d'Informàtica (IMI), the body responsible for the Ajuntament's technology systems, has been tasked with running the deduplication process alongside an external contractor. The contract, valued at under €200,000 according to procurement records published on the city's transparency portal, covers both automated hash-matching to identify pixel-identical duplicates and a manual review layer for near-duplicates where editorial judgment is required.

Three Decisions That Will Define the Outcome

Three choices now sit in front of city officials, and each one carries political as well as technical dimensions. The first is whether to centralise the image library entirely under IMI or maintain distributed departmental control with shared standards. Centralisation would be faster and cleaner, but several departments — particularly those tied to the Pla Estratègic de Turisme de Barcelona and the Institut de Cultura de Barcelona — have historically resisted losing autonomy over their own communications assets.

The second decision concerns how aggressively to replace removed duplicates with new commissions. The city's existing framework contract with local photographers, renewed in March 2025, covers documentary work across all ten districtes but has a gap in coverage for hyperlocal neighbourhood imagery in areas like Nou Barris and Sant Andreu, which are chronically underrepresented in official materials.

The third, and most consequential, question is about public access. The city must decide whether a cleaned-up, deduplicated image library becomes fully open under a Creative Commons licence — as civic tech advocates at groups like Codi Obert Catalunya have been pushing for — or whether a tiered access model protects certain commercial uses. That choice will land on Collboni's desk no later than September 2026, when the audit's final recommendations are scheduled for presentation to the Consell Municipal.

The next 90 days will determine whether Barcelona ends up with a genuinely interoperable, legally clean visual archive or a tidier version of the same fragmented system. Either outcome will set a template that other Spanish municipalities, including Madrid's Ayuntamiento, are already watching closely.
