Howdy, y'all, and greetings once again from beautiful Tuscaloosa,
Alabama, located between Aventine and Palatine hills along the banks
of the beautiful river Tiber. :P
Today's post is going to be a tad bit quick -- I spent the day
speaking to Cobb County's (GA) art teachers at Atlanta's High Museum
of Art, and those teachers plum wore me out -- but I really think
you're going to enjoy the sites that I have dug up for you. :)

Image Search Engines
--------------------
By now, everyone knows about Google. And, if you have been riding our
little bus of Internet happiness for a while, you also know about
Google's free browser buttons
http://www.google.com/options/buttons.html
as well as Google for the US Government, Linux., Apple, BSD, and
colleges and universities:
http://listserv.aol.com/cgi-bin/wa?A2=ind0101A&L=tourbus&P=R299&m=100 .
In fact, I've written so much about Google over the past year that
you'd think that there's NOTHING else I could add.
WRONG! Google just started beta testing a free image search engine at
http://images.google.com/ .
You heard right, folks: Google for *IMAGES*! YAY!
Google's Image Search works just like any other search engine. Key in
a term or phrase and up pop the results. Only this time, instead of
links to other Web sites, you see thumbnail images. Click on the
thumbnail to see a larger version of the image.
According to Google, "Google's Image Search is the most comprehensive
on the Web, with more than 250 million images indexed and available
for viewing." Yikes. That is a BUNCH of images.
My only complaint is that Google's Image Search isn't entirely family-
friendly; as Google warns, "[t]he results you see with [Google's image
search] may contain adult content." If this is a problem and you want
to use a family-friendly image search engine instead, check out either
Ditto
http://www.ditto.com/
or AltaVista's Image Search at
http://www.altavista.com/sites/search/simage .
If you do use AltaVista, though, make sure that the family filter is
on. You can find the filter link in the upper right corner of
AltaVista's yellow image search box.
---------
Now What?
---------
Okay. You've found an image you want. Now what?
Well, you can always "borrow" almost any image you see in your Web
browser by right-clicking (or, on a Mac, holding down the Control key
and then clicking) on the image that you want. A pop-up menu will
appear, and one of the choices will be something like "Save Picture
As" or "Save Image As." Choose that. This lets you save the image to
your computer. It's as simple as that.
Now, before you start celebrating, there are two nasty little things
that could hinder your little image-stealing spree:
1. Copyright; and
2. Image quality.
Let's deal with copyright first. As Google warns,
The images identified by the Google Image Search service may be
protected by copyrights. Although you can locate and access the
images through our service, we cannot grant you any rights to use
them for any purpose other than viewing them on the web.
Accordingly, if you would like to use any images you have found
through our service, we advise you to contact the site owner to
obtain the requisite permissions.
In other words, while all of the image search engines give you access
to an exciting treasure trove of images, before you can legally reuse
any of those images you need to both find and get permission from the
person who owns those images. That's pretty simple, though. If you
see an image on the Web that you want to swipe, just send an email to
the person who created that particular Web page. Most Web pages have
email links that let you contact the page's creator, and most Web page creators
are more than happy to give you permission to reuse their
images (heck, most Web page creators are more than happy that you took
the time to even visit their Web page).
As for the image quality problem, have you ever printed an image that
you downloaded from the Web? Looked like poo, didn't it? Want to
know why?
When professionals create images for print, they usually use something
called "CMYK mode" (a process that combines the primary pigments cyan,
magenta, yellow, and black) and use the highest resolution possible (at
least 300 dots per inch, and usually MUCH MUCH higher). That's
fine and dandy, but high resolution CMYK images are absurdly large, so
large that you wouldn't want to wait for them to download. So, CMYK
is best left to the paper world.
When it comes to images that are displayed on your computer screen --
for example, images that you view in your Web browser -- these images
only use three primary pigments: red, green, and blue (RGB). So,
off the bat, screen images aren't quite as vibrant as print images.
To make matters worse, to ensure that the graphics that you see in
your Web browser download as quickly as possible, the resolution of
these graphics is set absurdly low. In fact, the standard for
Internet graphics -- "gifs" and "jpegs" -- is a measly 72 pixels per
inch.
What does this mean in English? Internet graphics not only look like
poo, they look like poo as viewed through a rusty screen door! :)
How do you fix this problem? Unfortunately, you can't. That's one of
the limitations of Internet graphics.
I hope this helped. If you want to learn a little more about Internet
graphics, take a look at a free PowerPoint presentation that I created
called "Internet Graphics for the Artistically Challenged." You can
find it at
http://www.netsquirrel.com/classroom/ .
Make sure to read the "important information" at the top of this page
to learn how to both unzip and view all of my PowerPoint
presentations.
That's it for today. Have a safe and happy week, and we'll talk again
soon. :)
