Popular LightBox and Thickbox, JavaScript widgets to show content in modal windows, are outdated at the moment. They are not updated since 2007. There are some great alternatives - colorbox, jQueryUI Dialog, fancybox, DOM window, shadowbox, but we highly recommend you to try VisualLighbox - Lighbox Alternative. VisualLighbox is packed with a dozen of beautiful skins, fantastic transition effects and free gallery generator software for Mac and Windows!
