I’ve implemented a patch for next-gen gallery that allows you to display thumbnails independent of galleries. This does not replace the single-pic functionality, but is rather meant to complement it.
!BE SURE TO BACKUP YOUR PLUG-IN FILES BEFORE YOU DO THIS!
To install the patch, simply copy the ngg-functions.php file in zip below to your next-gen gallery plugin folder. If prompted, overwrite the existing file. This patch is for the 0.97 version, but it should work with other version with minor modifications.
–> Single Thumbnail Patch <–
Simply add “[thumbnail=x]“, where “x” is the id of the image you want to display, to any post or page. This will be replaced with a thumbnail of that image. You can find an example of usage at my site here.
Alex: Is there any chance this could be added as a permanent feature for next-gen?
