	// DefaultImages returns a list of default CommunityImage definitions for this ImageFamily.
	// Our Image Selection logic relies on the ordering of the default images to be ordered from most preferred to least, then we will select the latest image version available for that CommunityImage definition.
	// Our Release pipeline ensures all images are released together within 24 hours of each other for community image gallery, so selecting based on image feature priorities, then by date, and not vice-versa is acceptable.
	// If fipsMode is FIPSModeFIPS, only FIPS-enabled images will be returned

}

ImageFamily can be implemented to override the default logic for generating dynamic launch template parameters ATTENTION!!!: changes here may NOT be effective on AKS machine nodes (ProvisionModeAKSMachineAPI); See aksmachineinstance.go/aksmachineinstancehelpers.go. Refactoring for code unification is not being invested immediately.
