Title and canonical url for galleries

Hi,
Recently I’ve noticed my gallery title and canonical url has been changed to “gallery”. It was resolved before by your code from http://brimosoft.nl/2010/12/27/lazyest-gallery-and-seo-plugins/. After reading http://brimosoft.nl/2011/11/25/canonical-url-for-lazyest-gallery-1-1/ I’ve changed the code as said above. No luck, the gallery pages still showing “gallery” as page title. I know you are no longer support Lazyest gallery. I have tried upgrading to Eazyest gallery and failed. Almost everything ruined after downgrading to Lazyest gallery. Now I’ve re installed LG gallery. If you are still able to support this plugin, kindly guide me to get my title and canonical url back.
