I am looking to find out how to make the popups that some places have for images that take over the screen and usually has a background that has opacity that you can still see the original page below it. I can not find an example of this now that I actually need to use it. Does anyone know what I am talking about? Hopefully someone will read this and know what i am talking about.
Thats the AJAX based popups which are translucent and very effective as it does not get blocked by popup blockers. Search on google for AJAX scripts and you will find many.
