Image types
- .GIF
This is a compressed file format best used for compressing graphics with large
areas of solid color such as: logos, cartoons, navigation bars, line art without lots
of shading. GIFs have the ability to be made transparent, and to be animated.
- .JPG or .JPEG
This is a compressed file format best used for compressing graphics with colors that
fade or blur, and for photos. JPEGs cannot be made transparent nor can they be animated.
- .ART
An AOL proprietary format, not readable by people without AOL's browser. Please note:
AOL users using AOL's browser and proxy server will have all images converted into .ART for them
regardless of what file type that image orignally had.
Image size
The larger an image file size, the longer that image will take to load
when you go to the web page
You can reduce the file size of an image by making the image itself
smaller using a graphics editing program such as PhotoShop. You can also
reduce an image's resolution, measured in pixels per inch (PPI).
- An optimal image resolution for the web is 72ppi.
- An optimal image (file) size is 30K or less. The smaller the image,
the faster your page will be to load.
Note: The lab has a faster connection to the Internet than you probably
do at home so images will load faster there.
Getting an image onto your floppy
Get an image for use on a web page in one of the following ways :
- Use a digital camera to take a picture in JPG format.
- Go to one of the free graphics download sites listed below, click on
an image (right mouse click if on a PC, click and hold down on a Mac), and download it to your floppy
or zip (there might be a Save Image As choice):
Leave the image as a .gif or .jpg, but feel free to re-name the image to a
shorter name (you'll need to know its name to put it into your page).
- Use a scanner to scan in a photo and then use an image editing
program such as photoshop to make the photo the size you want it
and save it in a good size/resolution/format for the web. Usually
photos will be in the JPG format.
View your image locally
Just like with web pages, you can use your Netscape or Internet Explorer
to view your image locally. Go to the File menu and choose Open
and navigate to where your image is on your floppy.
Placing an image on a web page
To place an image on a web page you first must publish that
image on the WWW somewhere. So the first step once you have
that image on your floppy is to use FTP to publish that image
in your web publishing space. Please note, images must
be published using binary mode in WS_FTP and as raw data
in Fetch.
Choose your name for your image carefully. Use all lower case
to name images, and no spaces in file names. File names are case sensitive
and may not contain spaces.
After you have transferred your image using WS_FTP or Fetch, try
going to your URL for that image directly. If you have the web space
wpd1, and you published an image called deana.jpg, the URL for that
image would be:
http://www.meyerconsult.com/student/wpd1/deana.jpg
Decide what to do with your image
Images may be used as follows:
- An image that displays in a specific place on a web page
- An image that is used as a background to a web page and "tiles" to fill the whole
web page. Please note: using
an image as a background means that you cannot then use a background color.
To use a background image
To use a background image, that information goes in the BODY tag for your whole web
page. A web page may only have one body tag.
<BODY BACKGROUND="deana.jpg">
Using a photo as a baground can make it VERY hard to read the text on the page (see above
example).
To place an image on a web page
<IMG SRC="deana.jpg" ALT="A picture of Deana in a pink shirt" TITLE="Deana Meyer" ALIGN="RIGHT" >
Note: in quotes after the attribute SRC is the full path to the image. If your image is
the same folder/directory as the web page that is referencing it, then you can just use the
image's file name.
