Question

EXTjs中图片格式显示问题

1、这是url加载一个图片地址，显示图片
html: '<img border="0" src = "<%=basePath%>images/+"<%=request.getParameter("url")%>" width="600" height="468"/>'
这个能规定图片的大小格式
2、这是根绝传递的参数动态获取图片url，来显示图片
{
layout: 'column',
xtype: 'container',
items: [{
columnWidth:.5,
layout: 'anchor',
xtype : 'box',
id:'a',
autoEl : {
tag : 'img',
src: '<%=basePath%>'+"/"+"<%=request.getParameter("url")%>"
}
}
这个我怎么规定图片的大小啊。求高手指点
