First responders don't want you to put yourself in harm's way, but they do hope images and video will help provide details people sometimes don't remember.
Chicago makes history by allowing 911 callers to send photos or videos of the incidents from their cell phones.
The police department's crime-prevention information center first began receiving the images in September as part of a pilot program, according to the Chicago Sun-Times.
Since then, the office has received more than 30 images from callers, most of which are related to incidents related to property damage, according the Sun-Times.
The office reviews the images to see if they should be sent as evidence to first responders or detectives investigating the incident.
Officials would like to warn Chicagoans not to try to take pictures of shootings in progress or other violent incidents, because that may put their life in jeopardy. In those instances, a call or a text message is recommended.
