Google's Nano Banana Pro and Naden Integration for AI Image Generation and Editing

This video tutorial demonstrates how to leverage Google's Nano Banana Pro (also referred to as Nano Banana 2), an advanced AI image model, within the Naden no-code automation platform to generate and edit high-quality images for free. The tutorial covers two primary use cases: creating new images from text prompts and editing existing images with specific modifications.

1. Generating New Images with Nano Banana Pro

The process begins with setting up a Naden workflow to generate a new image.

• Workflow Setup:
  • Trigger: A "Chat Message" trigger is selected. This allows users to input prompts directly through a chat interface within Naden.
  • AI Model Integration: The "Google Gemini" node is added, specifically choosing the "Generate Image" action.
  • API Key Configuration:
    • Users need to obtain an API key from Google AI Studio (aistudio.google.com/api-keys).
    • A free tier is available, offering a significant number of credits.
    • To ensure long-term free usage, users are advised to set up billing by agreeing to terms and selecting their country. This provides $300 in free credits, which is ample for extensive image generation and editing.
    • A "Gemini Project" needs to be created or selected.
    • A new API key is generated, named, and then copied to be pasted into the Naden credential setup.
  • Model Selection:
    • While Gemini 3 models might not be directly listed, users can input the model ID manually.
    • The specific model ID for Nano Banana Pro is models/gemini-3-pro-image-preview.
  • Prompting: The text prompt from the "Chat Message" trigger is connected to the "Prompt" input of the "Generate Image" node.
• Demonstration:
  • A prompt was used: "A 22-year-old male stands with a Yankees hat in front of a gym."
  • The generated image showcased high quality, with particular attention to the detail of the "New York Yankees" hat and the background "Metro Fitness" gym. The realism of the 22-year-old subject was also highlighted.
  • Another example prompt: "A 23-year-old female with a big hat in front of a dress shop." The generated image was praised for its accuracy, detail, and realistic appearance, including a "French boutique" in the background.

2. Editing Existing Images with Nano Banana Pro

The second part of the tutorial focuses on modifying existing images.

• Workflow Setup:
  • Trigger: A "Naden Form" trigger is used, specifically the "On a new Naden form event." This allows users to upload an image and provide editing instructions via a form.
  • Form Configuration:
    • Form Title: "Edit Image"
    • Form Description: "Edit images with Nano Banana Pro"
    • Form Elements:
      • "Description" (Text, Required): For user instructions on edits.
      • "Image" (File, Required): To upload the image to be edited.
  • AI Model Integration: The "Google Gemini" node is added again, this time selecting the "Edit Image" action.
  • Image Editing Configuration:
    • Credentials remain the same as for image generation.
    • "Resource" is set to "Image."
    • "Operation" is "Edit Image."
    • The "Prompt" for editing is linked to the "Description" field from the form submission.
    • The "Binary file name" for the image needs to match the name of the file upload element in the form (e.g., "image").
• Demonstration:
  • An image of a male with a Yankees hat was uploaded.
  • The prompt provided was: "The girl in the image holds a coffee cup wearing a baseball hat." (Note: The prompt mistakenly referred to "girl" while the image was of a male, but the AI still processed the request).
  • The edited image successfully showed the subject holding a coffee cup and wearing a baseball hat, while maintaining the original background and other details of the image. The change from a "large hat" to a "baseball hat" was also noted.
