This is how users will submit their product images and model preferences.\n\n2. **Configure your [OpenRouter](https://openrouter.ai/) API credentials**\n   Add your OpenRouter API key in the **HTTP Request** node credentials. This connects to Google's Gemini model for image generation.\n\n3. **Verify image processing settings**\n   The workflow automatically handles base64 conversion and file processing through the **Code** and **Convert to File** nodes. No additional configuration needed here.\n\n4. **Customize the output form**\n   Adjust the completion message and download settings in the **Form** node to match your branding.\n\n5. **Test with sample product images**\n   Once configured, upload product images to generate high-quality advertisements featuring models using your products.\n\nOnce all connections are set, your workflow will **accept product images, generate professional advertisements with models, and deliver downloadable results** 🚀"
