Our prompt instructs the model on how to compose the final image.\n* Gemini generates a new image but uses the original 3 assets to do so. The consistency to the source images is very high and shows little signs of hallucinations!\n* Gemini's output is base64 so we use a \"Convert to file\" node to convert the data to binary.\n* The final binary image is then uploaded to Google Drive to complete the demonstration.\n\n### How to use\n* The manual trigger node is used as an example but feel free to replace this with other triggers such as webhook or even a form.\n* Technically, you should be able to compose even more images but of course, the generation will take longer and cost more.\n\n### Requirements\n* Gemini account for LLM and Image generation\n* Google drive for upload\n\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!\n\nHappy Hacking!"
