IDT Include Files

You place these files into the the directory that contains your calendar files. You should find a couple of .IDT files distributed with your calendar software.

iFrames to embed calendars in web pages
iFrames permit your web pages to pull the contents of other web pages into table cells and other html structures. This allows dynamic calendars to be part of your web page content. Here are a couple of examples of what can be done with this technique.

Embed a mini calendar

Embed a full week community calendar

Displaying the source of these web pages will show how iFrames are used to accomplish the effect.
Adding Graphical Images
Adding graphical images to your calendar is easy to accomplish. It is requires embedding a small amount of html into the text that is to appear on the calendar. The images to appear can be located anywhere, but it is easiest if you put these images into the iCal installation folder.
Example for an image in your calendar directory
This code will work because the image ical2.jpg is installed with iCal program. Use this as the text for a calendar event.

<IMG SRC="/ical2.jpg"> Cool!

Example for an image located somewhere on the network

<IMG SRC=""> Cool! `

Side Bar Menu
There is a clever trick that can be used to get a menu along the left side of your calendar. This is accomplished by putting html code in the calendar header and footer. Below are samples for the header and footer. You can customize these to your own needs. Sample Menu Calendar is the result of using the header and footer code below.

This goes in the calendar header
<table width="100%" background="/images/background.jpg">
<tr><td>Side Bar Content goes here...</td>

This goes in the calendar footer
Yes, the table tags don't match up; the calendar generates some that fit together with these. You may need to experiment a bit to get it looking right :-)
