Now supports Internet Explorer 6! Thereby, it is compatible with Lightroom under Windows when Internet Explorer is left at version 6, since Lightroom 2.x on an XP installation always renders web galleries using Internet Explorer, even if another browser is installed. (It is quite common that people may have the latest version of Firefox, but Internet Explorer is left at version 6 and that's what Lightroom will use to render html content inside Lightroom.)
This also widens the audience of your web gallery: visitors using Internet Explorer 6 will see the web gallery rendered the same way as in Internet Explorer 7.
