网页间怎么传递图片：添加在RadioButtonList中的图片，一张网页中点击按钮，下一张中显示出来！
麻烦大侠写写具体代码！感激不尽！
<asp:RadioButtonList>
<asp:ListItem<img src ="tu/5.jpg"></asp:ListItem>
</asp:RadioButtonList>

<asp:RadioButtonList id="RadioButtonList1" runat="server">
<asp:ListItem Value="tu/5.jpg">
<img src="tu/5.jpg"></asp:ListItem>
</asp:RadioButtonList>

============================
private void Button1_Click(object sender, System.EventArgs e)
{
string tmp = Server.UrlEncode(this.RadioButtonList1.SelectedItem.Value);
Response.Redirect("webform2.aspx?imgpath="+tmp);
}

=============================

webform2:
string tmp = Server.UrlDecode(Request.QueryString["imgpath"]);
this.Image1.ImageUrl = tmp;
