A base url also called a base href, is used in the head section of a page like this:
<head>
<base href="http://www.website.com/images/" />
</head>
So in this example any images used in the page would only need <img src="imagename.gif" />
and they will display in the page.
You can also use the following to open pages when links are clicked:
target=_blank" for a new window
target =_parent" to open a page in a parent frameset
target="self" to open in the same window
target="_top" to open links in the full body of the window.
Note that this is limited to the following doctype DTDs S=Strict, T=Transitional, and F=Frameset.
