 * @changeLog:{
 * [adrian]:[28.07.2010] - added LoadImages and LoadDropdowns used for Network Page and My Groups
 * [bogdan]:[02.09.2010] - modified ValidateName to validate name with nordic characters
 * [adrian]:[05.10.2010] - added deleteAlbum
 * [adrian]:[11.03.2010] - added hideExistingObjects - used for search to add people in groups
 *	Network page
