Some of his original coding is a bit grating to a perfectionist such as me :) However, I find the self reference (var flickrUrlsObjPointer:FlickrUrls ) that enables him to reach to the parent object in onLoad a nice touch. Actionscript 2 is still a mess though as far as readability.
For the unitiated, all we are trying to do is to capture the output from a REST call such as this: http://www.flickr.com/services/rest/?method=flickr.urls.getUserPhotos&api_key=404d98e10174604c8050f4f732e2162e&user_id=66489324%40N00
Via a XML object – the expected response is something like this
user nsid = “66489324%40N00” url="http://www.flickr.com/photos/zzkj/”
