Hi jon,
Here's the blurb from the changelog on getting the Cooliris 3D gallery going:
Added PicLens support. Use [piclens] in your Custom Layouts to get the PicLens link, or use attribute piclens=true in the photosmash shortcode to get the link without tweaking a custom layout. If you’re going the shortcode route, you can also use the attribute piclens_link=’Start Slideshow’ for the text of the piclens link…use whatever text you’re wanting in place of Start Slideshow. It will default to ‘Start Slideshow’ with a little piclens icon.
If you need to do it without a gallery, you should be able to get the URL if you set up a gallery as instructed above and display it. You can remove it after you get the URL you need.
