How can one group/link 2 sets of thumbnails together?
For example:
Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text
[thumb id="4,5,12"]
Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text
[thumb id="13,16,20"]
Both set of thumbnails displays the "next/previous" option (with 3 pictures in the set) when clicking on one of the thumbnails.
How can I link these two together (without placing them in a single set, the text MUST remain in between), so the next/previous shows 6 pictures.
