"content": "## Refresh product photos for slow-selling Shopify products with Dreem.ai\n\n### How it works\n\nThis workflow runs monthly to find Shopify products that have recent sales underperformance, then refreshes their product imagery with Dreem.ai. It batches the slow-moving products, generates fresh on-model photos, waits for render completion, and publishes completed images back to Shopify. Slack notifications report skipped renders and the overall refresh completion.\n\n### Setup steps\n\n- Configure the schedule trigger for the desired monthly run time and timezone.\n- Connect Shopify credentials with permissions to read orders/products and update product media.\n- Configure Dreem.ai credentials and the image-generation settings used by the \"Generate Fresh On-Model\" node.\n- Connect Slack credentials and select the channels or users for skipped-item and completion notifications.\n- Review the custom code in \"Find Slow Movers\" to ensure the slow-selling criteria match the store's sales and inventory strategy.\n\n### Customization\n\nAdjust the slow-mover logic, batch size, render wait duration, Dreem.ai prompt/style settings, and Slack message content to fit the catalog and merchandising workflow."
