On http://wordpress.com/blog/2008/04/04/new-dashboard/ there was a topic on 'Built-in galleries'.
With more info on http://codex.wordpress.org/Using_the_gallery_shortcode
A few days ago, I've uploaded some pictures with the 'multi-file upload'. I didn't wrote a post at that specific moment. Now, today I want put all those pictures in to one gallery as described above using the
[gallery id="...."] code.
How can I find the 'ID' for those pictures/gallery?
