Receives a `query` string field via the Execute Workflow Trigger (passthrough mode).\n2. Sends the query to **Google Gemini** to generate a professional, photorealistic image.\n3. Uploads the resulting binary image to your **WordPress Media Library** via the WP REST API.\n4. Returns `url`, `media_id`, and `alt` to the calling parent workflow.\n\n### Setup\n1. Connect your **Google Gemini (PaLM) API** credential to the **Gemini \u2014 Generate Image** node.\n2. Connect your **WordPress API** credential to the **WP \u2014 Upload Image to Media Library** node.\n3. Update the WordPress URL in that node to point to your site: `https://your-site.com/wp-json/wp/v2/media`.\n4. Call this workflow from a parent workflow, passing a JSON field named `query`.\n\n### Customization\n- Change the Gemini model in **Gemini \u2014 Generate Image** to adjust image quality or style.\n- Edit the prompt prefix in the same node to change the default photorealistic tone.\n- The filename in the `Content-Disposition` header uses a timestamp \u2014 adjust as needed.\n\n\u26a0\ufe0f **Community Node Notice:** This workflow uses `@n8n/n8n-nodes-langchain.googleGemini`, a LangChain community node. It requires a **self-hosted n8n instance** with the LangChain add-on installed."
