Recently we could see the new pop window open when u click on ur pictures. most of the people feels that its not good to look at. they would like to use the old photo viewwer insted of the new one
switch to old photo viewwer:
when u click a photo on facebook u will see that picture thru that pop up window. at that time refresh the page by hitting F5 key on ur keyboard. thats it ur old photo viewwer is ready.
