So I started at https://gemini.google.com and uploaded a photo of a woman with the Dutch prompt: “Kan jij deze dame in een Feyenoord-fan veranderen, met een voetbalveld en vuurwerk in de achtergrond? Iets grappigs? (En een Amsterdammetje paaltje erbij.)“
Basically, I ask the AI to change her into a fan of Feyenoord, a local soccer club. With some minor details. And I expected Gemini to start Nano Banana and then give me a picture. Instead, I got this, in English! 
I will generate an image that transforms the woman into a Feyenoord supporter in a stadium setting, while also adding the requested humorous element.
Subject: Focus on the same blonde woman from the original image (her face and expression), maintaining her identity but placing her in a new context.
Attire: Instead of her black top, dress her in an official Feyenoord fan jersey (red and white halves, “FEYENOORD” logo, and maybe a humorous custom sponsor name like “HET LEGIOEN” or “BIER TEAM”).
Accessories/Humor: Replace her serious expression with a joyful, cheering smile. Add red and white face paint. The humorous element will be her holding a sign that reads: “I ONLY CAME FOR THE BITTERBALLEN (AND THE WINS!)” and maybe a scarf draped over her.
Foreground Element: Place an Amsterdammetje (the distinctive brown bollard with the three white X crosses) unexpectedly and comically in the foreground within the context of the Rotterdam stadium, clearly marked as a misplaced object, perhaps slightly damaged or with a small “Amsterdam” arrow sticker pointed away from the pitch.
Background: Set the scene at a nighttime De Kuip stadium during a celebration. The pitch should be visible with players. In the stands behind her, large, colorful displays of red and white smoke pyrotechnics and fireworks are exploding, making the atmosphere chaotic and celebratory. Other fans (out of focus) cheer around her.
Style: A vibrant, high-quality photograph using natural stadium light mixed with the dynamic glow of the fireworks.
Perspective: A medium close-up, focusing on her reactions, the sign, and the bollard, while showing the depth of the stadium crowd and celebration behind her.
Language: Ensure all text (on the sign, the bollard, and the jersey) is correct in Dutch.
Lighting: Dramatic lighting from the pyrotechnics, creating rich colors and reflections on her face and jersey.
Details: Add a realistic stadium texture (seats, railings, crowd noise implied), and make the overall scene feel authentic yet slightly whimsical due to the out-of-place bollard.
Shot Type: Candid, dynamic photo capturing the joy and humor.
Focus: Sharp on the woman, sign, and Amsterdammetje; soft bokeh on the background crowd and fireworks.
Final Check: Ensure it’s the same woman (crucial for identity, use her features from the source photo) and that all four constraints are met: Feyenoord fan, football field, fireworks, and Amsterdammetje, while also incorporating humor.
Action: Generate the image with the specific instructions.
Prompt: “A vibrant, celebratory photograph featuring the blonde woman from image_0.png, with a wide, joyful smile and red/white face paint, standing in the middle of a crowded Feyenoord stadium during a night match celebration. She is wearing a Feyenoord jersey and holds a handmade sign in Dutch reading: ‘IK KWAM ALLEEN VOOR DE BITTERBALLEN (EN DE WINSTEN!)’ and a ‘FEYENOORD’ scarf. Behind her, other cheering fans fill the stands, and the football pitch is visible in the background where dynamic red, white, and gold fireworks and smoke pyrotechnics are exploding. In the immediate foreground, unexpectedly placed near her feet in the stadium aisle, stands an authentic Amsterdammetje (brown bollard with three white X crosses), marked with a funny, taped ‘VERKEERD GEPLAATST’ (Misplaced) sticker. A beer cup is held in her hand. The photo has dramatic stadium lighting and is sharp on her expression and the foreground elements, with natural crowd density and blurred, festive pyrotechnics in the distance. Real-life texture, candid, medium shot.”

And a lot more of this weird text…
So, there you have it, people! We’re driving Gemini nuts with our prompts! 
I edited the prompt, tried again and now I got a better result.
