must try to deduce the image’s contents by using other factors. Most of those factors are related to text on the Web site that stores the original image. Image Search uses the site’s URL, the image file name and folder name, page content, page title—none of which, of course, necessarily describe the image. Google’s search also looks for image ALT tags that a Web site designer might use during a site’s construction. These tags might provide a description of the image for older browser versions that can’t display images, or for browsers with the image display option disabled. How does Google find and sift through all of this data and then return your results so quickly? The answer is that it doesn’t—not in real time, anyway. Google uses automated software that continually downloads text from Web sites all over the world, and then it stores that text in large-capacity index computers. Those index computers act just like the index in the back of a nonfiction book. When you use Image Search, you’re actually searching the indexed data, which is why sometimes you see either outdated image information, or you find that Google isn’t yet listing an image that you’re sure is online. Those problems aside, Google’s Image Search is so massive that it will point you to thousands, even millions of images related to your keywords, a fact that makes this tool very handy during your online adventures. 36 www.smartcomputing.com / Guide To Using Google T HE S EARCH Basic inquiries. But what exactly makes a basic keyword search effective? With Google, the answer is easy. The greater number of effective keywords you provide in the search text box, the better. It takes practice to figure out what makes for effective keywords, but basically, the more precise and unique the words are, the more likely your results will be accurate. For example, using “cat” as a keyword will return millions of very varied images. Type “calico kitten,” however, and you’ll see a results list that’s much more focused. Notice that we didn’t include words such as “the” or “this” because Google throws out ultra-generic words, anyway. Sophisticated Searches The Advanced Image Search options are easy to use and will help you quickly filter out many irrelevant results. When basic keyword searches wind up providing you with too many unrelated results, you can use the advanced search capabilities within Image Search. These tools will help you refine and hone your searches so that Google will know what you’re looking for. Using the advanced Image Search features, you can specify image size, file type, coloration, domain, and you can apply a After you click a thumbnail, Google displays a screen with the thumbnail on top and the main image below. You can tell Google to remove the top frame at any time. SafeSearch filter that will sort out adult material. With one or more of these tools, you’ll quickly be able to change your search parameters and find the images you really want. For example, let’s say you want to find a range of full-color images of the Hilton hotel located in Paris. Using a basic keyword search, such as “Paris Hilton,” you’ll get mostly modeling snapshots of the yellow-haired socialite, some of which might not be appropriate for younger viewers. But using advanced options, we cleaned up this search in a hurry. In the Related To All Of The Words text box, we typed “hilton,” and in the Related To The Exact Phrase text box we entered “Paris France.” Because we wanted only color images, from the Coloration drop-down menu, we selected Full Color. And to prevent the possibility of any explicit material, we also clicked the Use Strict Filtering option. This search was much more accurate, as Google returned dozens of images and maps of the Hilton hotel in Paris. And thanks to the filtering option, no adult-oriented images appeared. You should keep in mind that the SafeSearch filter in Google Image Search is powerful but imperfect. There are three SafeSearch settings: No Filtering, Use Moderate Filtering, and Use Strict Filtering. If you select No Filtering, Google won’t censor results at all. If you choose Use Moderate Filtering,
Google will omit most explicit images from your list of results. This is the default setting for Image Search. The Use Strict Filtering option should remove all explicit images from your image search results, and it will apply SafeSearch filtering to your ordinary Google Web searches, too. Like all filtering services, SafeSearch makes mistakes. That means potentially offensive images might appear in your list of results even when you’re using the Moderate or Strict settings. You should also know that SafeSearch filters out explicit material only if you’re executing searches in English. So if, for example, you run a few searches in Spanish, SafeSearch won’t filter your results at all. Engaging other options. The other advanced search options are useful, too. For example, if you want to restrict your results to images of a specific size, you can use the Size drop-down menu and select Small, Medium, or Large, which means that, respectively, you’ll see results of 150 x 150 pixels or smaller, images with dimensions between 150 x 150 pixels and 500 x 500 pixels, or images bigger than 500 x 500 pixels. The Size option is one of Image Search’s most valuable capabilities, because without it, Google will list images of all sizes in your results. If you’re looking for a high-quality image you can print at home, you’ll want to sort out the smaller images, many of which contain far too little data to let you create a clear print. And if you just T HE S EARCH Google offers three levels of image filtering to prevent explicit images from popping up onto your screen. The filter works only for English language searches. want a small- or mediumsized image for email purposes, this filter helps you weed out large images you’d need to resize. In addition to the Size option, you can use the File Type drop-down menu to sort by JPEG (Joint Photographic Experts Group), GIF (graphics interchange format), and PNG (Portable Network Graphics) file formats. This option is useful when you know the image you’re looking for is in a specific format, or when you want to download an image and you only want one file type. The Domain filter lets you limit Image Search results to one Web site or domain. For instance, you could search only domains such as .edu or .com, or you could search only CNN.com for a specific news image. This option is especially useful when your searches turn up too many unrelated images from all over the Web, or when you know for sure that an image is located on a specific Web site or domain. Breakin’ the law. In addition to the possibility that Google will lead you to explicit material no matter what SafeSearch option you engage, Image Search might also point you to other potentially problematic graphics. Because Google’s robotic image indexing scheme is so effective, it often links to images protected by copyright. That’s no crime on Someone took the time to create the images you see on Image Search, and that means those images could be protected by copyright. Don’t reproduce the images you find with Google until you obtain the creator’s permission. Google’s part, because all Google does is let you view these images on the Web. But it means you should take precautions if you plan to download and use an image for your own purposes. If you see an image that you find useful, you can follow the thumbnail back to the Web site that’s storing the image to see if there are any indications that the image is copyrighted. If you don’t see any notice of copyright, don’t assume that it’s OK for you to download the image and incorporate it into a product brochure you’re designing. Not only is this kind of behavior rude and insensitive to the person who created the image, but you might also be using an image that doesn’t have a clearly marked copyright notice. The only way to be sure you’re not violating copyright laws when you use an image from the Web is to contact the site’s owner and ask for permission. Once you have a go-ahead from the image’s creator, you won’t have to worry about being on shaky legal ground. At The End Of The Day When the Web was in its infancy, finding multiple images on one subject often took a lot of investigative work. In the era of Google’s Image Search, finding a specific graphic or image is as easy as typing a few keywords. With just a little practice you’ll be able to find the exact images you’re looking for with minimal frustration. RS BY NATHAN CHANDLER Reference Series / Guide To Using Google 37
