【【【【【【图片问题顶也有分！！】】】】】】

最近我在做一个关于图片上传  显示的项目  正好这里也有好多兄弟在发这方面的帖子
所以我想收集一下关于图片上传显示这方面的资料最好是 SQL数据库  加  C#代码的（别的数据库和语言的也可以）大家可以提供链接
提供代码
提供思路
或者完整的项目下面是主要内容  只给一部分也谢谢主要内容就是  图片  如何上传到服务器
图片  如何显示给客户端
图片  怎样在客户端生成缩略图
图片  如何做成链接   点小图放大为大图
图片如何放在DataGrid里
如何对图片的一些细节处理  等等等等等等等等等等等等等等等等等等等等等反正凡是跟图片有关的项目  代码  思路网站   尽管放过来   我照单全收   呵呵有意者加我QQ：8453605  或者发我信箱：[email protected]嫌分少的  再开N帖也不是问题

2. 在ASP时代要上传一个文件是很麻烦的事,有了ASP.Net事情就变得简单.这里我给出一个实例,希望能对朋友们有帮助.文件上传的实例, 来自http://www.chinabs.net">中国BS网<%@ Import Namespace="System.IO" %>
<%@ page Language="C#" debug="true" %>
<html>
<head>
<title>上传文件 , http://www.chinabs.net </title>
<script language="C#" runat="server">
//This method is called when the "upload" button id pressed
public void UploadFile(object sender , EventArgs E)
{
   //检查上传文件不为空
   if(myFile.PostedFile!=null)
   {
  string nam = myFile.PostedFile.FileName ;
  //取得文件名(抱括路径)里最后一个"."的索引
  int i= nam.LastIndexOf(".");
  //取得文件扩展名
  string newext =nam.Substring(i);
  //这里我自动根据日期和文件大小不同为文件命名,确保文件名不重复
  DateTime now = DateTime.Now;
  string newname=now.DayOfYear.ToString()+myFile.PostedFile.ContentLength.ToString();
  //保存文件到你所要的目录,这里是IIS根目录下的upload目录.你可以改变.
  //注意: 我这里用Server.MapPath()取当前文件的绝对目录.在asp.net里"\"必须用"\\"代替
  myFile.PostedFile.SaveAs(Server.MapPath("\\upload\\"+newname+newext));
  //得到这个文件的相关属性:文件名,文件类型,文件大小
  fname.Text=myFile.PostedFile.FileName;

4.在以前的Web应用中，上传文件是个很麻烦的事，现在有了.NET，文件上传变得轻而易举。下面的这个例子实现了多文件上传功能。可以动态添加输入表单，上传的文件数量没有限制。代码如下：MultiUpload.aspx<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MultiUpload.aspx.vb"

    <title>多文件上传</title>
    <script language="JavaScript">
    function addFile()
    {
     var str = '<INPUT type="file" size="50" NAME="File">'
     document.getElementById('MyFile').insertAdjacentHTML("beforeEnd",str)
    }
    </script>
  </HEAD>
  <body>
    <form id="form1" method="post" runat="server" enctype="multipart/form-data">
      <center>
        <asp:Label Runat="server" ID="MyTitle"></asp:Label>
        <P id="MyFile"><INPUT type="file" size="50" NAME="File"></P>
        <P>
          <input type="button" value="增加(Add)" onclick="addFile()">
          <asp:Button Runat="server" Text="上传" ID="Upload"></asp:Button>
          <input onclick="this.form.reset()" type="button" value="重置(ReSet)">
        </P>
      </center>
      <P align="center">
        <asp:Label id="strStatus" runat="server" Font-Names="宋体" Font-Bold="True"

正在做图片处理的东西
包括：
1、图片的上传下载
2、图片的格式转换
3、图片的旋转、放大缩小、加水印
4、图片的特殊效果处理，含高斯模糊、水波、球镜、阴影、立体等
5、图片的合成（有很多功能尚无法实现）
6、水晶按钮、立体文字的处理（也只实现部分功能）等有待解决的问题：
1、图片的分层效果（类似PHOTOSHOP的Layer和Mask）[已找到部分解决方案，但仍有待处理]
2、文字的Emboss Bevel等处理
3、如何实现Illustrator,CoreDraw的部分效果
4、图片的任意变形，就象PHOTOSHOP中的Transform菜单下的很多效果一样，目前可以实现其中的几种变形，任意变形仍无法解决。
5、如何实现工具箱功能，类似VS，DreamWeaver,CoreDraw的左边可浮动的工具箱？
6、客户端FTP上传问题？
7、多图片压缩上传后的解压问题？
8、如何保存为矢量图形格式？欢迎大家探讨。
