[Plugin: NextGEN Gallery] NextGen: Need gallery thumbnails in post to click to gallery subpage

When I add a nextgen gallery to a WordPress post, the thumbnails open the image on the post itself with back/next navigation below it. How do I modify this so that clicking the thumbnail will open the gallery subpage (which the gallery is already linked to in the settings) instead? Thanks in advance… this is driving me nuts!

Here is an example of the end result I’m looking for: https://sandrarose.com/2011/04/celebs-out-about-the-2nd-annual-steve-harvey-foundation/

When you click the gallery thumbnail (or the single pic) it goes to the gallery subpage instead of opening the gallery on the post.
