What it does
- Subscribes to a configurable image topic and saves a .jpg when a trigger service is called.
- Offers a standard std_srvs Trigger service and a string-trigger service that adds a filename suffix.
- Accepts both raw Image and CompressedImage messages, switching between them if one source stops supplying frames.
- Publishes a status topic once per second describing the image stream.
- Limits stored captures by file count and total storage size, with zero meaning unlimited.
- Provides a launch file with arguments for topic, output directory, node name, namespace, and limits.
