FAQPage Schema
How do I generate images from text prompts using Gemini?▼

Text-to-image generation with Gemini uses the Gemini 2.5 Flash Image model to create images from descriptive prompts. Provide your text description, configure aspect ratio and safety settings, and the Skill outputs images to ./docs/assets/. You'll need a Gemini API key via google-genai.

Can I edit existing images or combine multiple images into one composition?▼

Yes, the Skill supports image editing by modifying existing images through prompts and multi-image composition that combines up to three input sources into a single scene. Both workflows output to ./docs/assets/ with configurable aspect ratios.

What do I need to get started with text-to-image generation?▼

You need API key access to Gemini through the google-genai dependency, a text prompt describing your desired image, and optional configuration for aspect ratio and safety settings. The Skill handles output management to ./docs/assets/.

How does iterative refinement work with Gemini image generation?▼

Iterative refinement enables dialog-based interaction with the AI model to progressively improve generated images. Submit a prompt, review the output, then refine through follow-up prompts until the result meets your design needs.

What are the limitations of multi-image composition with this Skill?▼

The Skill supports composition with a maximum of three input images combined into a single scene. Aspect ratios and safety settings are configurable, but composition is limited to this three-image constraint.

Can I use this for product photography and branding asset creation?▼

Yes, the Skill is designed for product photography, branding assets, and design workflows. Text-to-image, editing, and composition features support creating marketing materials and design collateral with configurable outputs.
