Generate Image Example

Steps to Create the Flow:

  1. Add a Start Node.

  2. Add and connect a Text Input for the image description.

    • Example prompt:
    A detailed cross-section diagram of a plant cell showing the nucleus, chloroplasts,
    mitochondria, cell wall, and cell membrane. Educational style with clear labels
    and bright colors suitable for middle school students.

  3. Add and connect a Generate Image Node.

    • Select Process Type: FLUX.1 [pro] for high-quality educational illustrations
    • Connect the Text Input's Output to Input

  4. Add and connect a Display Image node to show the generated image.

    • Connect the Generate Image's Output to Display Image

  5. (Optional) Add a Display Text node to show the image location.

    • Connect the Generate Image's Image Location to Display Text

Result: Custom educational illustrations are generated from text descriptions, providing visual aids for learning materials.
