A "Lock this photo" button in the photos widget's dialog toggles PhotoWidgetConfig.locked, which suppresses both the timer-elapsed auto-advance and the advance/back button actions until unlocked. The Layout tab canvas shows a lock badge on any locked photo widget's box.

"""Photos widget: composes one photo from Immich into the widget's own
|
|
region -- the widget-system analogue of routers/device.py's old
|
|
_render_photos_mode/_advance_photos_mode/_back_photos_mode, and
|
|
app/photo_queue.py's real client.
|
|
|
|
render() never raises -- an Immich hiccup for this one widget shouldn't
|
|
take down the whole panel's render just because one region out of
|
|
several couldn't be composed this cycle; it falls back to a small
|
|
placeholder instead, the same resilience calendar mode's old photo-inlay
|

already had (see routers/device.py's `except HTTPException: pass` around
|

its own inlay fetch)."""
