I see a rotating banner graphic on almost every e-commerce site I go to these days. They usually consist of 3 or 4 slides that alternate featured products. I ve seen some source code that is freely available using CSS and javascript- but I d like to know is there is one particular source that is considered the best of the best?

Lean code- fast load time- as SEO friendly as possible. Can you recommend some places?

Thanks :)
Target.com is a great example- but they are using Flash. I d like to accomplish it without Flash.

I think its javascript at least. somethings say enable javascript to view- and i did enable through internet options and all that crap.and when i click on links- the bar at the bottom of the screen has the javascript commands- but nothing else happens. i have the latest version too. anyone know what to do?

I have the following pop-up on my website:

<SCRIPT language="JavaScript">alert("Be aware that this page automatically plays music upon entrance.") </SCRIPT>

How do I make it pop-up only once per browser session?
Can I just add something onto the HTML code??
