图片上传代码
❶ 图片怎么编写HTML代码上传到网上
我可能思想笨，没完全理解你的意思，
你是要在网页中插入图片<img>
在一个是用图片组建上传。
在一个把图片处理为二进制代码，存进数据库，然后通过程序把二进制翻译过来，（建议不要这样，）两张图片填满你的数据库，还有翻译来翻译去，效率很差。
❷ asp 上传图片 代码
我嘴笨 代码上！
protected void UpLoad(object sender, EventArgs e)
{
foreach (UploadedFile file in RadUploadContext.Current.UploadedFiles)
{
string Path = Server.MapPath(@"../../Uploads");
//如果路径不存在，则创建
if (System.IO.Directory.Exists(Path) == false)
{
System.IO.Directory.CreateDirectory(Path);
}
//file.GetName()取得文件名
string filename = file.GetName().ToString();
//取得文件名(包括路径)里最后一个"."的索引
int index = filename.LastIndexOf(".");
//取得文件扩展名
string extendName = filename.Substring(index);
//取得原文件名不包含后缀名
string fileNameFirst = filename.Substring(0, index);
//用当前时间为文件重名名,确保文件名不重复
string datename = DateTime.Now.ToString("yyyyMMddHHmmss");
string newFileName = fileNameFirst + datename + extendName;
//组合路径
Path = Path + "/" + newFileName;
//保存
file.SaveAs(Path, true);
this.dataurl.Visible = true;
this.lab2.Visible = true;
this.FileUpload1.Visible = false;
this.Button3.Visible = false;
this.dataurl.ReadOnly=true;
this.dataurl.Text = newFileName;
//Response.Write("f1：" + fileNameFirst);
//Response.Write("f2：" + Path);
}
}
前台：
<th>上传文件：</th>
<td class="style1">
<asp:TextBox runat="server" ID ="dataurl" Width="50%" Visible="false"></asp:TextBox>
<asp:FileUpload ID="FileUpload1" runat="server" Width="65%"/>
<asp:Button ID="Button3" runat="server" Text="上传" OnClick="UpLoad" Height="25" Width="25%"/>
<asp:Label ID ="lab2" runat="server" Text="上传成功!" ForeColor="Red" Visible="false"></asp:Label>
</td>
❸ 怎么把图片上传到网站上，然后可以提取图片代码
你把这张图片放到QQ的相册里，然后右键它的属性，就会有一个地址，用这个地址就可以了
❹ 上传图片代码修改

❺ 上传图片到服务器如何写代码
设计里拖一个FileUpload和以个Button
然后在Button_Click事件里写
string FileName = FileUpload1.PostedFile.FileName.Substring(FileUpload1.PostedFile.FileName.LastIndexOf(@"/")+1);//获取文件名字，前面的盘符路径省略；
FileUpload1.PostedFile.SaveAs(Server.MapPath("要上传的盘符名" + FileName));
❻ 求JAVA上传图片代码
package com;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
import com.jspsmart.upload.*;
public class uploadfiles extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException
{
//使用了一个第三方的组件，存放在web-inf/lib下
response.setContentType("text/html;charset=GB2312");
//由于SmartUpload的初始化方法需要pageContext,所以我们在servlet中得到他
//为了得到pageConext要首先得到JspFactory的实例
//通过JspFactory的实例的getPageContext方法得到pageConext的实例
JspFactory jf = null;
//得到JspFactory的实例
jf=JspFactory.getDefaultFactory();
/*
getPageContext(Servlet servlet,
ServletRequest request,
ServletResponse response,
java.lang.String errorPageURL,
boolean needsSession,
int buffer,
boolean autoflush)
*/
PageContext pageContext=jf.getPageContext(this,request,response,null,true,8192,true);
try
{
//实例化SmartUpload
SmartUpload mySmartUpload=new SmartUpload();
//初始化SmartUpload的实例，需要PageContext的实例
mySmartUpload.initialize(pageContext);
//设定最大上传的字节数，其实可以不进行设定，表示上传的文件没有大小限制
//mySmartUpload.setTotalMaxFileSize(10000000);
mySmartUpload.upload();
//下面是单文件上传
//上传的文件以com.jspsmart.upload.File 代表，如果文件名称重复，则进行覆盖
com.jspsmart.upload.File file=mySmartUpload.getFiles().getFile(0);
String upLoadFileName=file.getFileName();
//调用com.jspsmart.upload.File实例的saveas的方法保存文件，此时的文件名即是
//保存到服务器上的文件名
file.saveAs("/upload/"+upLoadFileName);
Request req =
Text t = .....;
t.setUpload(upLoadFileName);
t.set.....(req);
}
catch(SmartUploadException e)
{
System.out.println(e.getMessage());
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException
{
doGet(request,response);
}
}
❼ asp图片上传求代码
留邮箱
❽ 在html页面里面制作一个上传图片的区域，就是点那个区域，就能上传照片，这个html代码应该怎么写
你好，html上传文件的代码如下：
<inputtype="file"name="fileUpload"/>
<inputtype="submit"value="上传文件"/>
至于你要说的有个区域显示图片的，这个需要配合前端开发才可以，单纯的html代码是做不到的，谢谢。

❿ 请问，上传图片的源代码怎么写还有，怎么上传本地图片
文章里贴图有两种方法： 1，网络图片链接：在文章编辑时，点击上面功能区中的“插入图片”在对话框中粘贴网络图片地址，确定即可显示。钩选显示源代码即可看到“图片的源代码”。 2，本地上传图片：编辑文章时，点击下面的“图片剪贴板”—浏览—找到你计算机中准备好的图片后，选中确定，然后随光标插入图片即可。需要注意的是本地上传图片要求一定是“jpg和gif格式的，容量不能超过200KB”。 上面的两种方法都可以使用，而且钩选显示源代码，都可以看到图片添加的代码，复制下来就可以了。
