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.
