Chuck,
When the application using the lightbox javascript is contained in an iframe on a parent page, it doesn't work normally. The window may pop up in front of everything, but that 'everything' does not fade to black like it would normally. If you visit the link I posted to the site where I use my existing photopost license, you would see what I mean.
I have a new application for photopost on a different site, but I would need to place the photo gallery in an iframe on a parent page. Clearly that does not produce the desired result when using lightbox integration.
I did some more digging and I found lytebox, which addresses this very problem.
Lytebox - Home
Here's what they say about lytebox on that page:
iFrames: If you plan to use Lytebox in an iFrame environment, then you need to include lytebox.css in the parent document, while including lytebox.
js in the iFrame document.
Before I bought a second photopost license, I was just hoping to get some insight as to whether or not photopost using the lightbox integration, could be made to behave properly.
