這個是將落葉語法修改而來的下雪語法，將圖片從落葉改為雪花！

說明↓
grphcs=new Array(1);  <==這是指有多少張雪花照片
Image0.src=grphcs[0]="http://c.blog.xuite.net/cf/7b/11732000/blog_698/txt/4517029/0.gif";  <=這是那張雪花圖的網址，你如果設grphcs=new Array(3);  那就要有三張圖的網址定義！像是↓
Image0.src=grphcs[1]="網址";
Image0.src=grphcs[2]="網址";

Amount=4;  <==這是指有版面上有多少張雪花照片在飄落！(越多越吃瀏覽者的電腦資源喔！會拖不動！所以要小心)

setTimeout('fall()',200);  <==這是指雪花飄落的快慢，越小越快！！

耶誕節快到啦！要不要加個雪花呢？！
