Answer 1

The image you're talking about corresponds to the leftCalloutAccessoryView property of MKAnnotationView.
Extract from the doc :
leftCalloutAccessoryView The view to
display on the left side of the
standard callout bubble.
You can implement a methods such as this :
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation {
MKAnnotationView* annotationView = nil;
MyAnnotation *myAnnotation = (MyAnnotation*) annotation;
NSString* identifier = #"Pin";
MKPinAnnotationView* annView = (MKPinAnnotationView*)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if(nil == annView) {
annView = [[[MKPinAnnotationView alloc] initWithAnnotation:myAnnotation reuseIdentifier:identifier] autorelease];
}
UIImageView *leftIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"LeftIconImage.png"]];
annView.leftCalloutAccessoryView = leftIconView;
return annotationView;
}
Hope this helps,

In your MKAnnotationView set the leftCalloutAccessoryView property
leftCalloutAccessoryView The view to display on the left side of the
standard callout bubble.
#property (retain, nonatomic) UIView
*leftCalloutAccessoryView Discussion The default value of this property is
nil. The left callout view is
typically used to display information
about the annotation or to link to
custom information provided by your
application. The height of your view
should be 32 pixels or less.
If the view you specify is also a
descendant of the UIControl class, you
can use the map view’s delegate to
receive notifications when your
control is tapped. If it does not
descend from UIControl, your view is
responsible for handling any touch
events within its bounds.
Availability Available in iOS 3.0 and
later. See Also #property

Answer 3

v.leftCalloutAccessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"img"]];
where v - is the view of your annotation(MKAnnotationView)
Or if you want complete solution - here it is:
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
NSString *Identifier = [NSString stringWithFormat:#"%f%f",annotation.coordinate.latitude,annotation.coordinate.longitude];
MKPinAnnotationView *annView= (MKPinAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:Identifier];
if (annView==nil) {
annView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:Identifier] autorelease];
}
if (![annotation isKindOfClass:[MyAnnotation class]]) {
return nil;
}
RightCalloutAccessoryBtn* rightButton = [RightCalloutAccessoryBtn buttonWithType:UIButtonTypeDetailDisclosure];
annView.rightCalloutAccessoryView = rightButton;
annView.leftCalloutAccessoryView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"img"]] autorelease];
annView.canShowCallout = YES;
return annView;
}
You should write this code on the class of your map's delegate
