Can anyone tell me how the ads that appear to be just images moving across the screen without any borders are made? They look like they must be made on a transparent layer that "Pops-Up" for a set period of time then closes. I see it all the time on Yahoo.com these days. Is there a program that is being used to create these?

I believe most of them are created with JavaScript. Matt matt@bbcomputing.co.uk www.bbcomputing.co.uk

I know JavaScript can do that with static images and/or windows but the one I saw that really made me want to know how it was done looked like a video or a really good animation that had a guy appear from the left side of the screen and "Run" across the screen to the right side. It then made him kind of shrink into an ad that was small and had no borders. The whole time you could see what the underlying web page content was. Can JavaScript do that sort of thing?

Ive never done anything that complex but i know it is a pretty powerful language. Here is a page that has some simple floating animations on it... http://www.dynamicdrive.com/dynamicindex3/snow.htm It may give you an idea of how the more complex ones are done.

I think it would more acurately be described as DHTML (Dynamic HTML) which is a combination of JavaScript/CSS/HTML. In the example you cited I am guessing that the main component used was layers where you can have content overlap other content on a page.

Yes DHTML can do many advanced things like creating those floating menus you see and mouse trails, stuff like that. A floating "video" like you are describing could be done using an animated gif or (correct me if i am wrong) a flash animation. Matt matt@bbcomputing.co.uk www.bbcomputing.co.uk
