Version:           2.1.1 (using KDE 4.7.2) 
OS:                Linux

== Background ==

Each album might contain some pictures that should not be indexed as thumbnails or shown in the embedded preview or in the editor (eg. company confidential pictures of a business trip or nudie pictures of the ex-girlfriend)

However, they should be kept in same album as the other pictures.

== Requested feature ==

 * Tool to mark selected pictures as hidden
 * Hidden pictures should not be displayed (neither in timeline, slideshow, geo-search nor in any advanced search)
 * pictures hidden in digikam should also be hidden in the filesystem (a hidden folder would be sufficient, IMHO)
 * Something like a button could be displayed for each album to display potentially hidden images
 * This button could ideally be protected by a password
 * The tool should be able to remove the "hidden-status" of those pictures, so that they are treated as all the other pictures

The intention is to prevent pictures from being accidentally displayed and shown to "unauthorized" users e.g. in a slide show. There is no intention to have hidden images encrypted.
