Add image to the left of my annotations - iphone

Question

I have created annotations that show up perfectly on my map but I am not sure how to implement the leftCalloutAccessoryView to show images.
MapViewAnnotation.h

mapView.mapType = MKMapTypeHybrid;

}
// When the view loads

[locations addObject:myAnn];

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = #"MyLocation";
if ([annotation isKindOfClass:[PlaceMark class]]) {
MKPinAnnotationView *annotationView =
(MKPinAnnotationView *)[myMapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc]
initWithAnnotation:annotation
reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
UIImageView *imvLeft = [[UIImageView alloc] init];
//Set Image
[annotationView setLeftCalloutAccessoryView:imvLeft];
return annotationView;
}
return nil;
