Currently, Azure Container Registry does not provide a way to clean hoarded images in the registry. The count of the images are increasing as the automated build pipelines run, and most of these images won't be used in major versioning. So, regular cleaning is necessary to save space in repository. According to proposal here, the feature for managing lifecyle of images will be included in the service in future, but this script saves time till that time.
