This final prompt is given to Imagen 3.0 to generate the images.n* A quick webpage is put together with the generated images to present back to the user.n* If the user provided an email address, a copy of this HTML page will be sent.nn### How to usen* Ensure the workflow is live to share the form publicly.n* The source image must be accessible to your n8n instance - either a public image of the internet or within your network.nn### Requirementsn* Gemini for LLM and Imagen model.n* Cloudinary for image CDN.n* Gmail for email sending.nn### Customising this workflown* Feel free to swap any of these out for tools and services you prefer.n* Want to fully automate? Switch the form trigger for a webhook trigger!nnn### Need Help?nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!nnHappy Hacking!"
