Set it to `7` for weekly, `14` for bi-weekly, etc. The **Summary Start Date** anchors the interval — summaries are sent on that date and every N days after. For example, setting the start date to a Monday with an interval of 7 sends summaries every Monday.

 When Telegram media is enabled, an optional image can be attached to the summary message. By default, the official Immich logo is used. Set the **Summary Image URL** to empty to send text-only notifications.
