<p>When I downloaded Skype, I noticed that, in place of a normal "disk image" icon, there was a custom icon, and when I double clicked on the icon, the window used a colorful image as the background, prompting me to drag the skype icon into the applications folder.</p>

<p>How can I do that with my applications?</p>

<p>Thanks,
Jason</p>
