Images

People may expect your personal web page to contain a photograph of you, your family and pets, or your favorite possessions. It's not difficult to add an image to a web page once you have a digital copy of it. You have a few options for digitizing photographs:

  1. Take a print to one of the CIT Public Computer Labs and use a scanner and a program called Photoshop to scan the print, then save it as JPEG or GIF format (JPEG format is better for photographs). It may take some significant time to learn how to use the Photoshop software to result in a good scan so be sure to allow some time to experiment.

  2. Take a print to a commercial service, such as a local copy/media shop and have them scan it for you and save it (on a ZIP disk, floppy diskette, magneto-optical disk, etc.) in either JPEG or GIF format (JPEG format is better for photographs), so that you can transfer it to your home computer .

  3. Have film developed onto a CD or diskette that can be read directly by your computer; many places that offer film developing services can do this instead of, or in addition to, paper prints. If your computer has no CD drive, you can use a computer in one of the CIT Public Computer Labs to access the CD's images.

Although it's not hard to digitize images, it can be difficult to reduce the size of such files to a point where someone accessing your web page can see them within a reasonable amount of time. Compressing files can improve transfer rate, but can lead to loss of quality. If you wish to find out more about compression settings that result in significant file size reduction while keeping high quality, take a look at the Bandwidth Conservation Society's page. Once the image is on your machine, you can use your webpage developer to include it in your webpage.

Java Applets and JavaScript

Developing Java applets (self-contained programs embedded within a web page) and JavaScript code (instructions executed by the web browser) requires some programming skill. Using Java Applets and JavaScript within CU People web pages is permitted, so if you wish to implement either you are welcome to do so. For more information see the Java and JavaScript pages published by their developers.

Image Maps

"Image maps" are images within a web page that have defined areas that link to other pages. Such an image can depict a traditional map, but it can also show a diagram, photograph or artwork. To create an image map, you decide what areas within the image are to be linked, then use a program to define their shapes (rectangle, circle, polygon or point) and sizes. For each area defined, you enter the web address that should appear when a visitor to your page clicks the mouse in that area.

There are two types of image maps: client-side and server-side; both are permitted on the CU People system. Server-side image maps require the web server to interpret and act on the mouse click whereas client-side image maps rely on the web browser for the same response. The latter is more efficient, but not all web browsers support client-side image maps. Most web editors have features that create client-side image maps.

To use a server-side image map, your map file should then be saved and named with the extension .map. To link your image as a server-side image map, use the HTML format shown in the following example:

<a href="http://www.people.cornell.edu/pages/netid/image.map">
<img src="http://www.people.cornell.edu/pages/netid/image.gif" ismap>
</a>

Note that images defined as image maps may be either GIF or JPEG images.

Sounds

Digitized sound files can be included within a web page for those who wish to add a personal greeting or include some original composition for others to hear. Many modern systems come with built-in microphones that can be used to record sounds. See your system's manual for further information about using it to record audio input. In addition, certain on-campus lab facilities maintain sound recording and developing equipment. Once you have the sound you want on your machine, you can use your webpage developer to include it.
