"content": "## Image Compressor using Tinyfy API\n\n### How it works\n1. A schedule trigger runs every morning at 08:00 and generates a unique `processingId` for the execution.\n2. The workflow lists all images in your Google Drive **Input** folder that need to be compressed.\n3. Each file is downloaded and sent to the **TinyPNG/Tinify** API.\n4. The compressed image is downloaded and saved into the **Compressed** folder in Google Drive.\n5. The original files are moved to the **Original Images** archive folder.\n6. A log entry is created for each image in the **Data Table**, including: `fileName`, `originalSize`, `compressedSize`, `imageId`, `outputUrl`, and `processingId`.\n7. When all images are processed, the workflow retrieves the logs for the current `processingId` and generates an HTML report.\n8. A summary email is sent via **Gmail** with processing statistics and total memory saved.\n\n### Setup steps\n- [ ] Create three Google Drive folders: **Input**, **Original Images**, and **Compressed**, then update their folder IDs in the Google Drive nodes.\n- [ ] Create a **Data Table** (e.g. \u201cImage Compression\u201d) with fields: `fileName`, `originalSize`, `compressedSize`, `imageId`, `outputUrl`, `processingId`.\n- [ ] Generate a **TinyPNG/Tinify API key** and add it to the HTTP Basic Auth credentials used by the **Tiny URL API Call** node. - [API Documentation](https://tinypng.com/developers/reference)\n- [ ] Configure your **Gmail** credentials and the recipient address in **Send Report**.\n\n### Customisation\n- Adjust the schedule of the **Daily at 08:00 am** trigger as needed.\n- Update the HTML template in **Generate Report** to add your own branding, logo, footer, or email styling.\n"
