+## When to read this
+Use this if you want to explore photos, like them, or share them—and understand the filters.
+
+## Open the gallery
+Tap **Gallery** in the bottom navigation to see all event photos.
+
+## Understand filters
+- **Latest:** Most recent uploads.
+- **Popular:** Photos with the most likes.
+- **Mine:** Uploads from your device.
+- **Photo booth:** Visible only when the event enabled photo booth uploads.
+
+## View a photo
+In the photo detail view you can:
+- **Like** (heart)
+- **Share** (share icon)
+- **Download** (download icon)
+
+## Sharing photos
+- **System share:** Send via WhatsApp, Messages, or other apps.
+- **Copy link:** Generates a share link for the photo.
+- **Expiry:** Share links can expire; you’ll see an expiration message if that happens.
+
+## Public gallery
+Some events provide a public gallery link (e.g., `/g/<token>`). Access is time-limited and may expire.
