Just wondering how easy, or difficult, it is to create a customisable horizontal image slider which has descriptive text over the top of each new image? Also, would that text be picked up by SE bots or would it have to become part of each individual image?

Secondly, how about a vertical table type of slider such as that used on the twitter home page? I have a static table on one of my sites that has to be manually updated via CMS. But was thinking it would offer much more ro visitors if the table could scroll thus showing more data dynamically. Also, would this sliding text in tables get picked up by SE bots or ignored?

If such things are a bit too complicated for a novice to knock up from scratch (I've gotten a bit overwhelmed searching online), then perhaps someone reading this knows of tool or script that could be purchased to create the above items more easily?

Thanks in advance
