I picked up on a link to this blog with a lot of information on this and other related topics from the Lightroom News site (www.lightroom-news.com
) This link will take you directly to a discussion on embedding LR galleries into existing web pages, Bluefire Blog
The porfolio section of my web-site has been completely redone with LR galleries, if you are interested.
The only glitches I have come across so far are that the galleries refuse to load on machines running Win XP and Firefox. and the current discussion seems to only allow you to embed at a fixed size... my galleries are sized for 1280 x 1024 and can't be viewed without scrolling or viewing fullscreen (F11 on Windows) at lower resolutions.
