Please forgive me if this is not a lightbox2 issue.
I am using imagefield + imagecache + lightbox2 to display images on my website. Google has not crawled any of my images, despite the site being up several months. All my websites with this particular setup are experiencing the same problem. It may be due to the link structure that lightbox2 generates. Stella's homepage has different link properties, but I'm not sure if she also uses imagefield and imagecache. I am using lightbox2 version 6.x-1.x-dev (2009-Jan-12).
Stella, would you mind if I sent you a link?
