Google’s Nano Banana: The AI tool to replace Stock Imagery Forever

Training materials are more than words on a screen. Research into learning design has shown that strong visuals increase recall, create context and make complex ideas easier to understand. Yet many organisations still rely on generic stock photography or staged images that bear little resemblance to their real workplace.

The result is predictable. PowerPoint slides look the same as every other presentation, eLearning modules feature the same smiling strangers as competitors, and brochures show workplaces that do not match the reality of day-to-day life. The lack of authenticity damages engagement and undermines the impact of training.

Introducing Nano Banana

Google’s new image generation model, Nano Banana, has been designed to address this gap. Built directly into Google Gemini, it creates photorealistic, brand-consistent visuals in just a few seconds. Unlike many AI image generators, Nano Banana is fast, professional and designed for use at scale.

The key strength is consistency. Upload a single photo of an employee and the model can reproduce that person in multiple training scenarios:

  • Delivering a safety briefing in a PowerPoint presentation

  • Appearing in an eLearning module with realistic workplace backdrops

  • Featuring in a compliance brochure or policy guide

  • Presenting on a company website or internal platform

Instead of anonymous office workers, the images show recognisable staff in familiar environments. Training materials suddenly feel authentic, relevant and tailored to the organisation.

We explored exactly how Nano Banana works and how quickly it can generate workplace scenarios in our latest video. See for yourself how this tool creates a complete library of visuals in minutes:

From Cost to Consistency

Traditional approaches to training visuals are expensive. Commissioning professional photography can cost thousands of pounds, while stock photo libraries charge hundreds for limited licences. Neither guarantees that the result reflects the real organisation.

Nano Banana flips that model. By using AI to create authentic, repeatable visuals, companies can build entire training campaigns without the cost or compromise of traditional photography. The result is not only financial efficiency but also cultural consistency: training materials across departments, platforms and years carry the same recognisable imagery.

The Next Step for Training Design

For decades, training visuals have been an afterthought: borrowed, staged or generic. Now, with AI image generation models like Nano Banana, organisations can create bespoke, branded content in seconds. The opportunity is clear.

The only question is whether companies will continue relying on generic stock photos, or choose visuals that truly reflect their people and workplace.
