The University policy on
copyright laws requires that you do not copy any material,
such as images, music, or software that you do not have a legal right
to. The University also subscribes to the
Digital Millennium Copyright Act
Provided that you have a legal right to the source text, one of
the most powerful ways to learn how to use the web is to use the
VIEW > SOURCE menu, copy the source to a file, and use that as a
template to build your own pages -- this is very effective.
Here are some sample archives for images and icons that you might peruse:
- An excellent source of images and icons is
Barry's Clip Art Server
- A good source of images is
Free Clip Art (but you do have to provide your email address and
make up a login id and password).
- Don't overlook the
Nasa Home Page which is a source
of many beautiful images which you can extract
(for example here
),
provided that
you give credit to the authors (as I have done here).
For some strange reason, the recent images appear to be stored in ".bmp"
(bitmap) format, and so you can save them as follows:
- Click on [Save As..] and store it in the desired directory
- Click on [Start] > Programs > Accessories > Paint and import the
file into MS Paint
- Then save it in ".jpg" or ".gif" format.
- Another good approach is to use a search tool, such as "google"
and search for phrases such as free clipart
By the way, you can often capture images directly from the screen
depending on what browser and operating system you use:
-
On a PC you
can print out all or portions of the screen. If you highlight
a window, then hold the ALT key down while pressing the
PRINT SCRN key (near the upper right corner of your
keyboard), it places the image in the "Clipboard". If you then
invoke an application, such as WORD, and click on EDIT >
PASTE, that window is copied into your WORD document, at
which point you can print it. If you press PRINT SCRN
without pressing the ALT key, the *entire* screen is saved in
the clipboard.
You can also save the WORD document as HTML and display it in
a browser. Or, you can invoke Microsoft PAINT, click on EDIT > PASTE,
and save it as a ".bmp" file. Then you could read it into some
graphics package, such as Paint Shop Pro, and save it as ".gif" or
".jpg".
-
On the Macintosh, you can expand an Internet Explorer or Netscape
image to fill the screen,
and then type [Command]-Shift-3, where [Command] is the curly symbol,
also the Apple symbol, on the Mac keyboard. This stores the entire screen
in a file named "Picture1" in the Macintosh HD. You can then read this
file into PhotoShop, select MODE > INDEXED COLOR, manipulate it as
you wish, and then use SAVE A COPY... to write it as a GIF file, or
use EXPORT to save it as a transparent GIF.
-
If
you use Netscape under Linux, you can save the image displayed by Netscape
using FILE > PRINT and select FILE as opposed to PRINTER, and then supply
a file name. It writes the displayed page in Postscript format.
There
exist tools in Unix and other systems that let you convert Postscript
to GIF or JPEG format so you can display it on the WWW.
Also, you can usually capture an Internet
Explorer or Netscape
screen in Postscript very much as you do in Unix
and convert it to another format, such as "gif".
To capture the browser page, you
- Click on FILE > PRINT
- Select "Print to File" in the print menu
- Save it to a convenient folder and then use SSH Secure Shell in ascii
mode
to send it to a C&C computer, such as Homer. From there, you can
either print it in Postscript or convert it to another format, such
as "gif" (see "Unix Graphic Tools" in R561).
