# Image Generation

Generate images from descriptive text prompts. Adjust resolution, steps, guidance, and output format.

## Front-end controls

<Columns>
  <div>
    ### Prompt

    * Placeholder: “Describe the image you want to generate…”

    ### Parameters (defaults)

    * Resolution: 1080x1920 (portrait)
    * Steps: 25 (1–50)
    * CFG scale: 7.5
    * Seed: Random (42 default, customizable)
    * Format: JPEG (PNG optional)
  </div>

  <div>
    ### Output

    * Preview and download (JPEG/PNG)
    * Save to Assets (Images)
    * Share: Copy link, or post to social channels

    ### Templates

    * Workflow templates by use case
    * Aspect ratio presets for social networks
  </div>
</Columns>

## Workflow

<Steps>
  ### Write a prompt

  Be specific about subject, style, lighting, and composition.

  ### Tune parameters

  Use defaults first. Increase steps for quality; adjust CFG for prompt adherence.

  ### Generate

  Start generation, then review. Re‑roll with a new seed if needed.

  ### Export or iterate

  Download the result or refine your prompt and generate variations.
</Steps>

## Best practices

* Keep prompts under \~200 characters for predictable results
* Use high-level style tags plus concrete details (camera, lighting)
* Prefer PNG when preserving transparency; JPEG for smaller filesize
* Pick aspect ratio templates that match your publishing channel
