Google Image search has long come under controversy for the amount of pornography that is available to find within its database. In order to help protect users Google introduced the “safe search” filter system which allows users to filter the results according to adult content. The filter has three settings, off, moderate and strict. The filter used to be accessed via a second page and an approval and confirmation window but now Google have simplified this process and have included a quick access safe search drop down option box which appears directly below the Image search box at the top of the page.
