求助ASP上传图片保存数据库的问题！跪求！！！
一个无组件图片上传程序 上传的图片是以当前时间命名的，然后把图片名字写入数据库,上传写入都没有问题，只是要修改这个上传的图片时，就是要更新这个图片时，最新生成的图片名是可以写进数据库的，但是这新的图片名直接就写在旧的图片名后面，而不是更新旧的图片名以下是所用到的ASP文件和代码
picture2.asp 这是文件名
<html>
<head>
<title>上传图片</title>

function check()
{
if(myform.file1.value=="")
{
alert("请点击浏览按钮，选择您要上传的jpg或gif文件!")
myform.file1.focus;
return (false);
}
else
{
str= myform.file1.value;
strs=str.toLowerCase();
lens=strs.length;
extname=strs.substring(lens-4,lens);
if(extname!=".jpg" && extname!=".gif")
{
alert("请选择jpg或gif文件!");
return (false);
}

跪求各位高手帮我看看是哪出问题了
以下图片是问题现象
--------------------编程问答-------------------- 'save3.asp
pic2=request("pic2")
在这里下一个断点，调试下。 --------------------编程问答-------------------- 这是ASP.NET版。不是ASP版。亲
你这好几个页面的代码，大半夜真没耐心看。
你仔细调试一下有关文件名或是重命名文件的地方。还有文件名写入到数据库的地方。
看下文件名是在哪一个步骤变成这样子的。然后再查故障前段代码。细心点很快找出来的
--------------------编程问答-------------------- 上传图片和生成图片名字都没问题 就是一写进数据库就不覆盖旧图片名 而是叠加写入。。。。 --------------------编程问答--------------------
这个断点怎么写 可以给个代码吗 或者帮修改下 谢谢了 --------------------编程问答-------------------- stop我也加入了 但没有任何反映啊 --------------------编程问答--------------------
断点怎么写？让你下一个断点调试啊。难道你不知道什么是断点，什么是调试么？ --------------------编程问答-------------------- 新数据添加时增加“图片上传”，后期修改时把“图片修改”与“其它数据修改”分开。
另外如果你非得在修改的同时修改图片，可以在写入数据之前，把之前的图片文件名取出来，以同名写入覆盖，但这样，上传的图片必须是同类型的，比如都是JPG图片
还有就是修改之前取出之前的文件名保存，新图片上传完成后，再多一步对你取出来的图片进行删除操作 --------------------编程问答--------------------
这代码我不是很会啊 能帮忙写写吗 大哥
补充：.NET技术 , ASP.NET
