How to modify the About box of my ebook?

In an ebook, you can display its About box by selecting "Help|About".
You will get this window:

Each time you start a new project∞, HTML Executable creates a default About dialog box. But you can of course customize it and insert your own text, images, links... The About box is actually a special HTML page.

Steps to modify the About box

In HTML Executable, open your project and

1. select "Publication Settings"
2. select "Behavior and Scripting" and in "System HTML pages", double-click on the "About Dialog Box" to open the HTML editor.
3. you can now modify the HTML code for the About dialog box. As you may see, the HTML can contain some HEScript and JavaScript codes. You should leave this code unmodified unless you know what you do.
4. click OK to save the HTML code and compile your project.

Example
Just insert some additional HTML code:
