//*****parameters to set*****
//into this array insert the paths of your pics.
//if there are only 2 images, set them two times i.e. 1/2/1/2
//imges=new Array ('pic01.jpg', 'pic02.jpg', 'pic03.jpg', 'pic04.jpg', 'pic05.jpg');
//picleft=50; //set this to the left position of your pics to be shown on the page
//pictop=50; //set thid to the top position of your pics to be shown on the page
//picwid=200; //set this to the width of your widest pic
//pichei=200; //... and this to the height of your highest pic
//backgr="#eeeeee"; //set this to the background color you want to use for the slide-area
//(for example the body-background-color) if your pics are of different size
//sdur=3; //time to show a pic between fades in seconds
//fdur=1; //duration of the complete fade in seconds
//steps=20; //steps to fade from on pic to the next
//startwhen=1;
// "startwhen" leave it at "null" to start the function by calling it from your page by link
//(sample: <a href="javascript:myfade();">slide</a>)
// or set it to 1 to start the slide automatically as soon as the page is loaded
//*****nothing more to do, have fun :)
