How to search images with Google

Google lets you use four syntax elements to focus your image searches. All four are the same ones used in Google’s regular Web search . Keep in mind that because image searches are something of a crapshoot, you’ll probably have to fiddle with these syntax elements till you find exactly what you’re looking for.

Intitle can be a good way to hone searches because it looks for your keywords in Web page titles, which removes some of the guesswork for Google about what a page contains. Use it like this: intitle:"taj mahal".
Inurl works strangely in Google’s Image Search, because when Google records the text on a Web page, it considers certain elements—like JPG extensions—as part of the URL. Thus, if you search the image bank for inurl:poker, Google might show
you a picture from the URL www.dogsplayingcards.com/velvet.html because that
page contains a picture called poker.jpg.

That weirdness aside, inurl is like intitle in that it can whittle your results from thousands or tens of thousands of images down to a manageable number, like a few hundred.
Filetype is available as a choice in the Advanced Image Search, too, although you can use it to search only for the formats Google keeps track of—JPG, GIF, and PNG.
The one trick you’ve got with this operator that you don’t have on the Advanced Google Images
Image Search page is that you can specify filtetype:jpeg or filetype:jpg, which gives you different results (the advanced page includes only an option for JPG). Use it like this: "poker chips" filetype:jpg.
Site is also part of the Advanced Image Search, and you can use it to limit your searches to particular sites or domains, which include segments of the Web like .com and .net, and also countries, like .au (Australia) and .fr (France). The site syntax is especially handy when you want to restrict your results to images from Web sites from a certain country, like this: sitcom site:UK, which gives you pictures from British sites. And if you know that something you want to see is somewhere on one large site, use it like this: friends site:nbc.com.
