How to get rid of ?phocaslideshow=1 in URLs?

[mashut]

Some of the pages are indexed by Google with ?phocaslideshow=0 at the end of their URL. Therefore sometimes duplicates occur (the same page with and without ?phocaslideshow=1 in its URL). How to remove these URLs with ?phocaslideshow=1 from the code in case I do not need the slideshow in the gallery at all?... Thanks in advance!

Hi, this should be a question on google search developers, I think Try to see some Google tool for testing it - if some part of your system creates such link then the robot will use it - so check your site parts which do this link
