You feed the module post permalinks in one of two ways:

Manual list – paste one Instagram post URL per line. Perfect when you want full control over exactly which posts appear.
RSS bridge feed – point the module at an RSS feed (for example from RSS.app or FetchRSS) whose items link to Instagram posts. The module fetches the feed on the server, extracts the Instagram links, caches the result, and stays in sync automatically.
Key features
No Instagram API key, app or login — uses the official public embed.
Two sources: manual URL list or automatic RSS bridge feed.
Two render modes: self-contained iframe (no external script) or Instagram’s embed.js.
Responsive grid with independent column counts for desktop, tablet and mobile.
Configurable embed height, grid gap and optional captions.
Server-side caching with a configurable lifetime for RSS mode.
Graceful fallback: if a feed refresh fails, the last good posts keep showing.
Optional “Follow” link to your profile below the grid.
Configuration problems are shown only to logged-in administrators, never to visitors.
Bundled stylesheet can be turned off so you can style everything from your template.
