Upload items are a sound or an illustration. They are integrated in the wiki article and can be recorded/edited by the visitor. Each upload item is identified by a number (called the "index"). When editing a wiki article, if one of the indexes has disapeared, the sound or the illustration will be deleted, that's why we must display a warning.
