//         this script enables you to use so many slideShows as you want to              //
//         have on your page without any extra-programming.                              //
//         Only you must do is to set the paths and image-names!                         //
//                                                                                       //

//         - so many slideShows as you want to have                                 	 //
//         - easy implementation in the sourcecode                                  	 //
//         - each slideShow has its own slideShowSpeed and crossFadeDuration        	 //
//         - choose between random or in the order                                  	 //
//         - set a fix picture at the start of a slideShow                            	 //
//																				         //
// important:																	         //
//	       - The slideShow MUST be initialized with the same number as the index    	 //
//           of the images it is containing!! example: images[1] = slideShowNr 1    	 //
