Additional Fields
Additional fields panel responsible for auto fill of additional fields the are supported by WordPress.
At the current moment there are 2 tabs:
Random Author - auto fill post by with random value the;
Auto images - auto image upload from selected folder and and placement of the link in to an appropriate field (presumably for WP template, which you don't neet to specify link to thumb)
Everything is simple and clear with first one so lets take a closer look at auto images:
Field name - additional images field name;
Images folder - images destination folder;
Forsed reduction to... - Seize to which selected images will be reduced to;
End if ran out of files - this will avoid delicate images in different articles.
