HTML Images
With HTML you can display images in a
document.
The Image Tag and the Src Attribute
In HTML, images are defined with the <img> tag.
The <img> tag is empty, which means that
it contains attributes only and it has no closing tag.
To display an image on a page, you need to use the
src attribute. Src stands for "source". The
value of the src attribute is the URL of the image you
want to display on your page.
The syntax of defining an image:
The URL points to the location where the image is
stored. An image named "boat.gif" located
in the directory "images" on "www.free-webmaster-resources.info"
has the URL: http://www.free-webmaster-resources.info/images/boat.gif.
The browser puts the image where the image tag occurs
in the document. If you put an image tag between two
paragraphs, the browser shows the first paragraph, then
the image, and then the second paragraph.
The Alt Attribute
The alt attribute is used to define an "alternate
text" for an image. The value of the alt attribute is
an author-defined text:
<img src="boat.gif" alt="Big Boat">
|
The "alt" attribute tells the reader what
he or she is missing on a page if the browser can't
load images. The browser will then display the alternate
text instead of the image. It is a good practice to
include the "alt" attribute for each image
on a page, to improve the display and usefulness of
your document for people who have text-only browsers.
Basic Notes - Useful Tips
If an HTML file contains ten images - eleven files
are required to display the page right. Loading images
take time, so my best advice is: Use images carefully.
