Gallery Configuration

All gallery structure is defined in content/gallery.yaml. Copy the example to get started:

cp content/gallery.yaml.example content/gallery.yaml

Tip

Prefer a visual interface? Enable the Admin Panel by setting ADMIN_PASSWORD in your environment. It provides a drag-and-drop page builder that writes to these same YAML files automatically.

Hero Images

Single image or crossfade carousel on the homepage:

# Single hero image
hero: 00000000-0000-0000-0000-000000000000

# Carousel (crossfade between multiple images)
hero:
  - 00000000-0000-0000-0000-000000000000
  - 11111111-1111-1111-1111-111111111111
  - 22222222-2222-2222-2222-222222222222

Standalone Albums

Albums shown directly on the homepage as cards.

Note

The thumbnail image for each album grid card is automatically synced with the explicit "Cover Image" you select for that album inside the Immich Web UI.

albums:
  - 11111111-1111-1111-1111-111111111111
  - 22222222-2222-2222-2222-222222222222

Subpages

Group multiple albums into named collections. URLs are auto-generated from the name. The overall Subpage Cover Image shown on the homepage is automatically inherited from the Cover Image of the first album inside its list.

subpages:
  - name: Japan # → /japan
    title: 'Trip to Japan' # Optional: overrides the page heading
    subtitle: '2024 adventures' # Optional: adds a subline under the heading
    albums:
      - 33333333-3333-3333-3333-333333333333 # Tokyo
      - 44444444-4444-4444-4444-444444444444 # Kyoto

  - name: Wedding – Smith # → /wedding-smith
    password: clientpass123 # Optional: subpage-level protection
    albums:
      - 55555555-5555-5555-5555-555555555555
      - 66666666-6666-6666-6666-666666666666:
          title: 'Private Highlights'
          password: 'album-secret-123' # Optional: album-level protection

Alternatively, you can use the object notation (recommended):

subpages:
  'Japan':
    title: 'Trip to Japan'
    subtitle: '2024 adventures'
    albums:
      - 33333333-3333-3333-3333-333333333333

Sections

When a subpage contains many albums you can split them into named sections. A typographic table of contents with anchor links is automatically rendered above the albums. Sections are fully optional — omit them and you get the standard flat grid.

Each section can have:

Field	Type	Required	Description
title	string	✅	Section heading + anchor name
description	string	➖	Optional subline under the heading
albums	list	✅	Album UUIDs (same format as regular albums)

Within the albums list you can use a plain UUID, a simple title override, or an object with title and password:

albums:
  - 'album-uuid' # → uses the Immich album name
  - 'album-uuid': My Title # → displays "My Title" instead
  - 'album-uuid':
      title: My Private Title
      password: 'secure-password' # → adds a password gate to this specific album

Full example:

subpages:
  - name: Japan
    title: Japan
    subtitle: 'Travel through a land full of contrasts.'
    sections:
      - title: Tokyo
        description: 'Megacity, neon lights, silence in the noise.'
        albums:
          - '33333333-3333-3333-3333-333333333333'
          - '44444444-4444-4444-4444-444444444444': Shinjuku at night

      - title: Kyoto
        description: 'Temples and bamboo forests.'
        albums:
          - '55555555-5555-5555-5555-555555555555': Fushimi Inari
          - '66666666-6666-6666-6666-666666666666'

      - title: Osaka
        albums: # description is optional
          - '77777777-7777-7777-7777-777777777777'

Note

Each section title is automatically converted to a URL-safe anchor (#tokyo, #kyoto, …). The TOC appearance (separator character, numbering style, section rule) is fully controlled by the active theme.

Grid Layout

Configure the photo grid globally or per-subpage:

# Global defaults
grid:
  columns: 3 # number of columns (default: 3)
  gap: 12 # gap in pixels (default: 12)
  aspectRatio: '1' # "1", "3/2", "auto", etc. (default: "1")
  layout: masonry # "masonry" | "uniform" | "showcase" | "filmstrip" | "editorial-flow"

subpages:
  - name: Japan
    grid: # per-subpage override
      columns: 4
      layout: uniform
      aspectRatio: '3/2'
    albums:
      - ...

EXIF on Hover

Show camera/lens/settings when hovering over photos (enabled by default):

exifOnHover: false # set to false to disable

Footer

Optional minimal footer with social links:

footer:
  name: John Doe
  instagram: johndoe
  email: hello@example.com
  website: https://example.com

About Page

Create content/about.md with YAML frontmatter:

---
portrait: asset-uuid-for-your-portrait
name: Your Name
location: City, Country
gear:
  - Camera Body
  - Favorite Lens
---

Your bio text here. Supports full Markdown.

Finding UUIDs

• Album UUIDs: In Immich, go to Albums → click an album → the UUID is in the URL bar
• Asset UUIDs: Click any photo → the UUID is in the URL bar

System & Security

Advanced system settings are configured via environment variables in your .env or .env.local file.

Rate Limiting

To protect against brute-force attacks and resource exhaustion, Immich Folio includes an in-memory rate limiter.

• RATE_LIMIT_RPM: Maximum requests per minute per IP (default: 1500 for general API, 120 for map data).

Trusted Proxies

If you run Immich Folio behind a reverse proxy (nginx, Traefik, Caddy, Cloudflare), tell it how many proxies sit in front. Without this, the rate limiter reads a client-supplied header and an attacker can pick their own bucket — defeating brute-force protection on the password endpoints.

• TRUSTED_PROXY_HOPS: Number of reverse proxies in front of the app (default: 0).

# nginx / Traefik / Caddy directly in front of the app
TRUSTED_PROXY_HOPS=1

# Cloudflare in front of nginx
TRUSTED_PROXY_HOPS=2

The client IP is taken that many entries from the right of X-Forwarded-For. Proxies append the address they actually observed, so everything to the left is client-supplied and ignored — a visitor sending X-Forwarded-For: 1.1.1.1 cannot influence which bucket they land in.

⚠️ The app must be reachable only through the proxy. Bind it to localhost (127.0.0.1:3000) or keep it on an internal Docker network. If clients can connect directly they control the entire header, and no setting can recover the real IP.

Matching nginx config:

location / {
    proxy_pass http://127.0.0.1:3000;
    proxy_set_header Host              $host;
    proxy_set_header X-Real-IP         $remote_addr;
    proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

$proxy_add_x_forwarded_for is the important one: it appends the real peer address rather than overwriting the header.

Migrating from TRUSTED_PROXIES

TRUSTED_PROXIES has been removed. It matched proxy IPs against the socket peer address, which a self-hosted Next.js server never exposes — so the check never passed. Setting it silently put every visitor into one shared rate-limit bucket, letting a single client trip the limit for the entire site. If it is still set, the app assumes TRUSTED_PROXY_HOPS=1 and logs a warning; replace it with an explicit value.
