For a Dynamic Slider use an RSS feed, preferably a featured content feed (forum or blog) as this will prevent un-wanted content from slipping into your slider. Also make sure all your content has an image, other wise it will show a default image. The Slider will automatically update as new content is added to your RSS feed.
Step 1) add a new text box, need more space see the Two Column Hero Box tip below
Step 2) go to wibbitz.com and add new player
Step 3) paste embed code (iframe) into your text box
In this example my slider is 430x250 next to a 300x250 ad, but you could make your slider any size by changing the width and height of the embed code.
There are some other options such as background music and voice-over (text-2-speach) which I don't care to use.
Improvements I would like see to wibitz
Two Column Hero Box
Insert the following in the middle column text box:
<div id="spotlight" class="space">ADD HERO CONTENT HERE</div>
