If you'd like to **place your logo in a specific corner**, feel free to _adjust the position_ of the overlay image in the code node.\n\n### How it Works\n\n1. Both images are downloaded, so we can process binary files (you can modify the source, tho.)\n2. We extract metadata, focusing on the dimensions of each image.\n3. The position of the overlay image is calculated (default: dead center of the background image).\n4. The two images are *composited* together.\n\n### Limitations and Optimization Opportunities\n\n1. The overlay image must be the same size or smaller than the background image for proper alignment.\n2. The overlay image does not automatically scale to match the proportions of the background image.\n\n![Image](https://cloud.let-the-work-flow.com/logo-64.png)  \nEnjoy the workflow! ❤️  \n[let the workf low](https://let-the-work-flow.com) — Workflow Automation & Development"
