You can (in general) "embed" relevant code in the HTML for video material (eg: hosted on youtube, or vimeo).
There are JQUERY and JS techniques for image faders and sliders.
We use BOTH on **this site**.
If you view that site's pages, go peek at the source code. Look at the HTML Headers for JS and CSS pointers, then see the relevant DIVS in the code for ideas on how to call the scripts on the page.
PS: Please don't ask us to walk you through these processes. The techniques used are common HTML principles. If you need lessons on HTML/JS/CSS, please visit w3schools.com as they have excellent tutorials on how to work with page code. (That's how we learned... This forum is for zencart-related help - not general lessons on HTML).
