FAQPage Schema

How do I generate high-quality prompts for GPT Image 2 and Nano Banana Pro?▼

Generating high-quality prompts for GPT Image 2 and Nano Banana Pro involves applying structured templates from a curated 255-prompt database. This approach streamlines workflows for diverse use cases including product posters, information graphics, and anime illustrations.

Can I generate images locally using a Node.js CLI and API keys?▼

You can generate images locally by running the included Node.js CLI script. After configuring your specific API keys, the script executes locally to produce the final image outputs directly from the generated prompts.

What types of image templates are available for structured prompt generation?▼

Available templates for structured prompt generation include 11 distinct formats covering product posters, information graphics, UI mockups, watercolor maps, and anime illustrations. These templates help drive high-quality image generation across various design contexts.

Do I need a specific database file to use the image prompt generation scripts?▼

Yes, accessing the prompts.json database file is required. The local Node.js skill relies on this database to execute the accompanying scripts for structured image prompt creation and data refreshing.

How do I refresh the data for my local image prompt database?▼

You refresh data for your local image prompt database by running a dedicated update script. This script updates the prompts.json file to maintain a current 255-prompt database for your generation tasks.

Are there limitations when using Node.js scripts for local image generation?▼

The primary limitation for local image generation using Node.js scripts is the mandatory API key configuration. Without valid API keys, the end-to-end workflow from prompt generation to output image creation cannot execute.
