Automate Lightroom to Instagram with Claude AI Alt Text Generator

Create a reusable “photos to post” queue from your Lightroom Cloud album—ideal for Lightroom-to-Instagram automation with n8n. It discovers new photos, stores clean metadata in a Data Table, and generates AI alt text to power on-brand captions and accessibility. Use it together with “Lightroom Image Webhook (Direct JPEG for Instagram)” and “Instagram Auto-Publisher for Lightroom Photos (AI Captions).”

What it’s for

Automate Lightroom to Instagram; centralize photo data for scheduled IG posting; prep AI-ready alt text and metadata for consistent, hands-free publishing.

Parameters to set

• Lightroom Cloud credentials (client/app + API key)
• Album/collection ID to monitor in Lightroom Cloud
• Data Table name for the posting queue (e.g., Photos)
• AI settings: language/tone for alt text (concise, brand-aware)
• Image analysis URL: public endpoint of Workflow 2 (Lightroom Image Webhook)
