我做了页面,用的是框架,我有框架的顶部放了张图片,和几个按钮,刚开始的时候,运行时图片可以显示就是在按按钮的时候有些闪(可能是重新载入),可后来不知什么大大原因,图片不显示了,按按钮的时候图片就一闪而过,也没改代码什么的,请各位帮忙说下,谢谢!

把你说的重点代码贴出来

public partial class title : System.Web.UI.Page
{
//public string str = "";
protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button7_Click(object sender, EventArgs e)
{
//Response.Write("<script language='javascript'>window.parent.location='index.aspx';</script>");

}
protected void Button1_Click(object sender, EventArgs e)
{
//str = "kh";
//Button1.PostBackUrl = "index.aspx?strName=" + str ;
Response.Write("<script language='javascript'>window.top.frames(1).location='khleft.aspx';</script>");
}

protected void Button2_Click(object sender, EventArgs e)
{
Response.Write("<script language='javascript'>window.top.frames(1).location='pjleft.aspx';</script>");

}
protected void Button3_Click(object sender, EventArgs e)
{
Response.Write("<script language='javascript'>window.top.frames(1).location='jjleft.aspx';</script>");
}

以上是我的代码,请帮忙说下

把你的图片的URL在page_load里写出来啊

怎么写呀,我没写过,请版主提示下

不起作用,我试过了

再放一个Lable什么的控件.
把 Response.Write("<script language='javascript'>window.top.frames(1).location='khleft.aspx';</script>");
这样的代码改成
Lable1.Text = "<script language='javascript'>window.top.frames(1).location='khleft.aspx';</script>");
试试.

注意:在Page_Load()里面写上Lable1.Text = "";
