Mouse over the Dope Sheet and press "Home" to see if that resets the view - sometimes the Editor can be zoomed making it appear as though nothing is present (although bone or control channels should still be shown). Otherwise it might just be that an appropriate Action hasn't been created yet as it is possible to create/edit/generate animations without Actions being duplicated for the Dope Sheet and/or Action Editor.
As an aside, when using flickr as an image host, select the BBCode 'share' option, those short codes don't work as they link to the page hosting the image rather than the image itself.
