There are some really good modal dialogs here:
jQueryUI Dialog is simple and very plain, but it is well supported.
Lightview is a real winner. It has a nice UI, some nice animations, and can “play” through a gallery. It can also handle just about any kind of content you throw its way.
ThickBox will take care of both your media and embeded markup. There are a lot of options, single image, gallery, as well as inline content, iFrame, and AJAX.
ClearBox is one of my favorites from a visual perspective. It’s standalone, and can handle all sorts of content types: Text, Image, Flash, Quicktime, Windows Media, HTML, and more. The image descriptions scroll by and the image gallery thumbs can be displayed while looking at the individual photos. There’s a lot here.
PyroBox will set your screen ablaze! This is very slick and smooth, and can handle many of your media needs, as well as inline and html content.
