This update to the superslider-show plugin provides a new option in the shortcode. You can now use the ids="12,13,14" option, so that it looks like this:
where the ids numbers are image id numbers from the media library.
The shortcode option of id="120,130" is still the same, where the id numbers are post id numbers.
This has been added in response to the new WordPress media gallery option of selecting various images from the media library to create a gallery of images.
so you can now have:
[gallery ids="12,13,14"] [slideshow ids="12,13,14"]
in the same post, first displaying the thumbs as gallery, then displaying the same images in a slideshow.
