Take a break from all that text and check out
Google Images
(http:///advanced_image_search)
does offer some interesting options.

Of course, any options on the Advanced Image Search page can be expressed via a little URL hacking ["Understand Google URLs" in Chapter 1].

Google's Image Search starts with a plain keyword
search. Images are indexed under a variety of keywords, some broader
than others; be as specific as possible. If you're
searching for cats, don't use cat
as a keyword unless you don't mind getting results
that include "cat scan." Use words
that are more uniquely cat related, such as feline
or kitten. Narrow down your query as much as
possible, using as few words as possible. A query like
feline fang, which would get
you over 75,800 results on Google, will get you only three results on
Google Image Search; in this case, cat
fang works better. (Building queries for image
searching takes a lot of patience and experimentation.) Search results include a thumbnail, name, size (both pixels and
kilobytes), and the URL where the picture is to be found. Clicking
the picture will present a framed page, Google's
thumbnail of the image at the top, and the page where the image
originally appeared at the bottom. Figure 3-1 shows
a typical Google Images result after choosing and clicking one of the
images found by your search.

Searching Google Images can be a real crapshoot because
it's difficult to build multiple-word queries, and
single-word queries lead to thousands of results. You do have more
options to narrow your search both through the Advanced Image Search
interface and through the Google Image Search special syntaxes.
