@Shady Elyaski's answer is great, here's a swift reinterpretation with Parse, incase anyone else needs a had.

    var eventThumb:UIImage?
    ...

    func mapView(mapView: GMSMapView!, markerInfoWindow marker: GMSMarker!) -> UIView! {


    ...
    //set up the rest of your view...
        if let eventImgExists = eventThumb {
                    eventImg.image = eventImgExists
                    self.eventThumb = nil
                } else {
                    if let currentEventThumb = currentEvent["thumbnail"] as? PFFile {
                        currentEventThumb.getDataInBackgroundWithBlock {
                            (imageData, error) -> Void in
                            if error == nil {
                                let image = UIImage(data: imageData!)
                                eventImg.image = image
                                self.eventThumb = image
                                self.eventsMap.selectedMarker = self.eventsMap.selectedMarker
                            }
                    }
                }
            }
