On the Google Images home page, you can search for an image by entering a query in the Search box and clicking the Google Search button Google Images searches for contextual information about the image, as well as any written content that appears near the image on the Web page; it doesn t have any way of searching the content of images themselves For this reason, you may need to finesse your search, framing your image searches with language that might be near your desired pictures Be aware that words have more than one meaning Although this is something to consider in all Google searches, pictures can be a lot more vivid (or inappropriate) than you might be expecting If you want to filter out inappropriate content, be particularly careful when you choose search terms For example, a search for the term disney bambi yields G-rated results, but a search for bambi alone might not Take a look at the section, Using SafeSearch with Images, later in this chapter for more information on excluding irrelevant or inappropriate content Because Google Images works by coming up with pictures that are nearby the text string you entered, search results can return people and objects not remotely in the search terms For example, the first image returned by a search for mark anthony julius caesar is an image neither of Mark Anthony nor of Julius Caesar as you might expect, but rather of Cleopatra, as you can see in Figure 8-2

The operators I explain in s 4 and 5 don t work with Google Images For more pinpointed searching, you can use the Advanced Image Search window, as well as a couple of advanced image-specific operators (see Using Advanced Image Search )

When you conduct a Google Images search, the search results page returns thumbnails of the images that Google Images found Each image on the search results page is captioned with its filename (and file format), the URL for the Web page that contains the image, the size of the image in pixels, and the size of the image file From this main image search results page, you can change your SafeSearch settings (see Using SafeSearch with Images ) and access the Advanced Image Search window (see Using Advanced Image Search ) You can also click each image on the search results page Clicking an image opens an image-specific results page like the one shown in Figure 8-3

There s something very important to understand about Google Images Just because you find a photograph (or other kind of image) using Google Images doesn t mean that you have any right to use the picture The pictures that Google Images finds are all on Web pages The content of these pages, including the pictures, are explicitly copyrighted (if there is a copyright notice on the Web page) or implicitly copyrighted (if there is no notice) Images (and other works of art) are legally copyrighted and owned whether a copyright notice appears on the page or not You have the legal right to view the Web page containing the picture However, that s the only clear legal right you have in relationship to the images that you find during your Google Images search Using images belonging to others happens all the time on the Web, and is often tolerated if there are no commercial issues involved Fair use guidelines do allow you to use copyrighted images in limited quantities for noncommercial purposes (to some degree including research) However, if you want to do anything with an image besides view it on the Web, and your usage is even potentially questionable, you should do the right thing and contact the copyright owner for permission Depending on the picture you re using, you might just save yourself a lot of grief by always asking for permission before using an image (Of course, this advice applies to all copyrighted materials, including written documents, audio and video files, and any other content that you find online) You can find out more about the US copyright laws and how they apply to images at wwwcopyrightgov You can find out about how international copyright laws might apply at the International Federation of Reproduction Rights Organizations, wwwifrroorg

Each image-specific results page shows a thumbnail of the image, as well as the Web page containing the image Technically, the image-specific results page is constructed using HTML frames The thumbnail is in a top frame, and the Web page containing the image is in a bottom frame The frames allow you to simultaneously view both the thumbnail of an image and the context in which it appears
