Generate AI images with Gemini and upload them to WordPress (sub-workflow)

🖼️ Generate AI Image with Gemini and Upload to WordPress Sub-workflow — Called by a parent workflow to generate a photorealistic AI image from a text prompt and upload it directly to the WordPress Media Library.

How it works 1. Receives a query string field via the Execute Workflow Trigger (passthrough mode). 2. Sends the query to Google Gemini to generate a professional, photorealistic image. 3. Uploads the resulting binary image to your WordPress Media Library via the WP REST API. 4. Returns url, mediaid, and alt to the calling parent workflow.

Setup 1. Connect your Google Gemini (PaLM) API credential to the Gemini — Generate Image node. 2. Connect your WordPress API credential to the WP — Upload Image to Media Library node. 3. Update the WordPress URL in that node to point to your site: https://your-site.com/wp-json/wp/v2/media. 4. Call this workflow from a parent workflow, passing a JSON field named query.

Customization - Change the Gemini model in Gemini — Generate Image to adjust image quality or style. - Edit the prompt prefix in the same node to change the default photorealistic tone. - The filename in the Content-Disposition header uses a timestamp — adjust as needed.

⚠️ 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.
