There are several JavaScript text slideshows around, including this one. If I want to put a slideshow of that kind on my website, would I need to add anything else other than some basic HTML?

Yes, there is a reason why I'm asking instead of just trying it. I'm quite inexperienced and I'm a lot older than you are and I'm just generally still full of dread every time I have to use an ftp program. Also, I'm worried that I do have to add something else and I'm dreading the failure that I'm probably going to run into. So I was hoping that someone here would be kind enough to just give me a hint and that failure a little less inevitable.

So I was just wondering . . . will the program work as-is, or will something have to be added to it?

Thank you in advance if you are the kind soul who will either offer me the necessary reassurance or the much-needed tip. . :-)
