Let's start with Flickr, since it's familiar to you from earlier discussions in
the topic and it consists mostly of photographs.
Flickr
Do you remember Flickr (lickr.com)? It's an online photo site owned by
Yahoo. It's searchable by tag, and search results are provided in an RSS
feed so that you can monitor new images as they're uploaded to the site.
As I mentioned earlier, this is a great place to try out those general search
terms that would provide impossible numbers of results on a general search
engine, but might give you surprising results on photograph search engines,
like screenshots or pictures of events.
tip
Flickr has enjoyed amazing success. perhaps because of that, there
are now many photo-sharing services to choose from. to check
out another photo service that offers rSS feeds of search results,
try SmugMug (smugmug.com).
Google images
Google used to crow about the extent of its image search (images.google.
com), noting how many images it had indexed and so on. It doesn't do that
now; instead it just primly notes that it has “the most comprehensive image
search on the Web.”
I don't know about that—there's really no way to compare it to other image
searches without an index count—but I do know a lot is indexed by Google,
in a lot of diferent formats. Google Images does not ofer an RSS feed of
its search results, so you have to narrow your search enough to get it in the
scope of a single page, and that means taking advantage of Google Images'
Advanced Search.
Google Images Advanced Search
he Google Images Advanced Search is available at images.google.com/
advanced_image_search. You can limit your search by color (you can
search for black and white, grayscale, or full color). You can also limit your
search by iletype—GIF, JPEG, or PNG. Photography is usually saved in
