Images and Links

One of HTMLs most important features is its ability to link from one document to another, and to incorporate links to images and other media within a document. These actions are controlled through the HTML tags described below.

To include an image in your message, use a tag of the form

<IMG SRC="filename ">

where filename is the name of the image file you want to appear at the location of the tag in your message. You can also add ALIGN="RIGHT" or ALIGN="LEFT" within the tag to cause the text to flow around the image, with the image being at the right- or left-hand edge of the window.

If you specify just a simple filename, then when you press the Save, Post or Preview buttons, the system will prompt you to upload the image file you have linked to. If all goes well, you should see the image within your message!

If the image already is on the web at another location, you can specify that web address (called a URL) instead of the file name. (URLs are the things that look like "http://www.somewhere.com/banner.jpg", and you can usually get these addresses from your browser's location bar when you are viewing the image on line.)

Similarly, if you want to link from your message to another web page, there is a special tag that makes that possible. In this case, it is of the form

<A HREF="url ">link-text</A>

where url is the address of the page you want to link to, and link-text is the text that will become the link within your message (most browsers show this as underlined blue text by default).

As with IMG tags, if the URL you link to is just a simple file name, then the system will prompt you to upload the file, and it will become a permanent part of your message.

As you upload files to become part of your message, they will appear in the Other Files list on the message form. As mentioned above, if you link to such files in your HTML, the system will prompt you automatically to upload them. If you need to move additional files (e.g., Java class files, JavaScript files, additional HTML files, etc.), you can do so using the Add button. The Remove button will delete the files you have selected in the list.

Please be considerate about the files you upload. This is not an invitation to store huge amounts of data, or images of questionable content (you know what I'm talking about). The system will not let you download executable files (e.g., CGI files, or .exe files), and your messages can not contain forms, server-side includes, or other tags that might allow you to execute commands on the server itself. You can, however, provide Java applets and JavaScript files, which run within the viewer's browser.
