I use it on many sites, but you can see a quick example on the RustyBrick Mobile Portfolio. Just click on the image and it opens up a larger picture of that image. Here is a screen capture showing the larger image as it overlays on top of the page:
The issue is, GoogleBot is having a tough time capturing these images in their index. WebmasterWorld administrator, Tedster, explained:
Tedster is exploring other ways to get GoogleBot to index Lightbox JS. He tried the following method, but it doesn't seem to work:
My latest attempt involves making the anchor part of the link a thumbnail image - but the thumbnail is not just a smaller version of the larger image. I use the same exact image file for the anchor, but I resize it on the the page with the HTML width and height attributes. This means that the page loads more slowly, but at least the image bot gets a direct <img src=[url]> style mark-up.
If you have a solution, let us know.
