手机微博 字数限制:这段代码怎么改

我想要把图片出现在页面的宽度和高度改一下
在哪改

<SCRIPT language=JavaScript1.2>
var slideshow_width=310 //SET IMAGE WIDTH
var slideshow_height=280 //SET IMAGE HEIGHT
var pause=3000 //SET PAUSE BETWEEN SLIDE (3000=3 seconds)
var fadeimages=new Array()
//SET IMAGE PATHS. Extend or contract array as needed
fadeimages[0]="图片地址"
fadeimages[1]="图片地址"
fadeimages[2]="图片地址"
fadeimages[3]="图片地址"
////NO need to edit beyond here/////////////
