rel="%GALLERY_NAME%"

In the Fancybox for WP plugin settings, on the Galleries tab I set it to “Do not group images in gallery automatically”. In this setting, Fancybox will only group images that have the same rel attribute, which Nextgen is putting in. This means I only get gallery grouping on my gallery pages and not on other pages (unless I edit the code manually for a particular post).

I was wondering how you modified the Next Gen and the Fancybox for WordPress, options to allow the rel tag for different galleries.

“The final tweak I made was to update the effect I was using for Nextgen. After some other experimentation I seem to have settled on the Fancybox for WordPress plug-in. This worked out of the box with Nextgen but I have adjusted the settings so that Nextgen adds a rel element to gallery images and Fancybox only groups images with the same rel (these are both easily setup in the settings for the plug-ins). I set this up so that I can control when images group if I have multiple images on the same blog post.”
