3.2. Google Images Advanced Search Interface
The Google Advanced Image Search (http://images.google.com/advanced_image_search)
allows you to specify the size (expressed in pixels, not kilobytes)
of the returned image. You can also specify the kind of pictures that
you want (Google Images indexes only JPEG and GIF files), image color
(black and white, grayscale, or full color), and any domain to which
you wish to restrict your search.
Image search also uses three levels of filtering: none, moderate, and
strict. Moderate filters only explicit images, while strict filters
both images and text. While automatic filtering
doesn't guarantee that you won't
find any offensive content, it will help. However, sometimes
filtering works against you. If you're searching for
images related to breast cancer, Google's strict
filtering will cut down greatly on your potential number of results.
Any time you're using a word that might be
considered offensive—even in an innocent
context—you'll have to consider turning off
the filters or risk missing relevant results. One way to get around
the filters is to try alternate words. If you're
searching for breast cancer images, try searching for mammograms or
Tamoxifen, a drug used to treat breast cancer.
