Oh, Nano Banana. The greatest AI image tool.

Here are 15 ways I use it to make ads:

1. Change hairstyle

Prompt: Mess up her hair so it looks like a full-on bad hair day: Uneven volume, frizzy strands, pieces sticking out in random directions and covering her face.

(By the way, you can access Nano Banana for free here)

2. Expand frame

Prompt: Zoom out to reveal her legs and more of the room she was painted in, while keeping the same original painting style.

3. Change outfits

Prompt:

Replace her dress with pink cozy pajamas covered in cute cat illustrations.

Replace her shoes with warm, furry slippers featuring a quilted texture.

4. Create mockups

Prompt:

Show the ad printed on a giant wall mural in Berlin. The mural covers the entire side of a building, with natural city lighting and realistic wall texture. Add a few Berlin street elements like bikes, graffiti, and a tram.

5. Add something shocking or unexpected
