1. 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。
2. 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。
