This small greasemonkey script I found today allows one to view all the Photos in Anyone’s album even if you are not his/her Friend , to use this you would need greasemonkey installed . graesemonkey is a Firefox addon , so unfortunately this hack can only be used in Firefox only. if you are a newbie to greaseMonkey then see the following Video first .
Once , you have seen that video I think you might be able to use GreaseMoneky , now just install this facebook hack script in your greasemonkey , just click on the green install button on the top right of the above page , while your greasemonkey is enabled to get it installed .
Once this is installed visit anyones page and you will be able to see the photos without his/her permission needed .
