In addition to a set of classes for writing CGI's and apache modules, groundwork provides the following useful images. To use these images in an application, copy them from /usr/local/firstworks/images to some place under your web server's document root and refer to them in an img tag.

invisible.gif is a 1 pixel x 1 pixel transparent gif, primarily useful for tabbing text over. Here is an example illustrating how to use invisible.gif for tabbing.

Here is the html used to construct this example.

<img src="invisible.gif" height="1" width="10">This text is tabbed 10 pixels over<br>
<img src="invisible.gif" height="1" width="20">This text is tabbed 20 pixels over<br>
<img src="invisible.gif" height="1" width="30">This text is tabbed 30 pixels over<br>

Tabbing can also be accomplished using the blockquote tag, but with the side effect of adding whitespace between rows. Tables can also be used, but using invisible.gif is simpler and less work for the browser.
