大家好，又见面了，我是你们的朋友全栈君。
网页必不可少的组成元素是什么？我想所有人都知道是文字和图片。
那么如何向网页中添加图片？会HTML和CSS的同学肯定知道，利用<img>标签插入图片，为src属性指定图片的相对路径，然后将图片放置到那个路径上去就可以了，例如下面的这个简单的HTML代码：
<!DOCTYPEhtml PUBLIC “-//W3C//DTD HTML 4.01//EN” “http://www.w3.org/TR/html4/strict.dtd“>
<html>
<head>
<meta http-equiv=”Content-Type” content=”text/html;charset=utf-8″>
<title> HTML内嵌图片教程</title>
</head>
<body>
<img src=”sea.png” width=”800px”height=”510px” alt=”sea” />
</body>
</html>
再加上一张好看的图片（sea.png）：
话不多说，下面我们来介绍如何将图片“嵌入”到HTML代码中，这样我们就不需要拷贝图片到指定路径下了，显示整张图片就只需要一个页面文件就可以了。
我们简单说下原理，我们知道，所有东西归根结底都是数据，图片也不例外，图片文件实际是由图片文件头，信息头（有的格式没有），图片数据，图片结束标识（有的格式没有）这些部分组成，在浏览器解析文件的时候，先到src指定的路径下将图片文件读取出来，然后按照图片头定义的文件压缩格式，对图片数据进行读取显示。所以我们可以直接将图片的内容进行编码然后存入HTML文件中即可。
HTML中支持base64编码的数据直接嵌入到网页中，这里提供一个网址，可以在线将文件内容转换为base64编码的数据，点击“choosefile”，然后点击“convertthe source data”，即可生成文件的base64编码数据。网址如下：
http://www.motobit.com/util/base64-decoder-encoder.asp
当然我们也可以手动编写一个小工具进行转码，C语言实现的base64编码方法如下：
char*base64_encode(char* in_str)
{
int i=0;
charbase64_table[]=”ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/”;
int curr_out=0;
if(in_len>0)
{
while(i<in_len)
{
char a=in_str[i];
char b=i+1>=in_len?0:in_str[i+1];
char c=i+2>=in_len?0:in_str[i+2];
if(i+2<in_len) /*余0*/
{
out_str[curr_out++]=base64_table[(a>>2)&(0x3f)]; //the first
out_str[curr_out++]=base64_table[((a&0x03)<<4)+(b>>4)]; //the first and the second
out_str[curr_out++]=base64_table[((b&0x0f)<<2)+(c>>6)]; //the second and the third
out_str[curr_out++]=base64_table[c&0x3f]; //the third
}
else if(i+1<in_len) /*余2*/
{
out_str[curr_out++]=base64_table[(a>>2)&(0x3f)]; //thefirst
out_str[curr_out++]=base64_table[((a&0x03)<<4)+(b>>4)]; //the first and the second
out_str[curr_out++]=base64_table[(b&0x0f)<<2]; //the last low 4 bits of the second
out_str[curr_out++]=’=’; //fill with the ‘=’
}
else /*余1*/
{
out_str[curr_out++]=base64_table[(a>>2)&(0x3f)]; //the first
out_str[curr_out++]=base64_table[(a&(0x03))<<4]; //the rest ofof the first
out_str[curr_out++]=’=’; //fill with ‘=’ in the lasttwo bits
out_str[curr_out++]=’=’;
}
i+=3;
}
out_str[curr_out]=’\0′;
}
return out_str;
};
调用时将文件内容读入char*，然后作为函数参数传入，函数的返回值即为编码后的结果。
这里我们将限于篇幅，将图像缩小为30像素×18像素后，得到的编码如下（仍然很多）：

然后，我们修改之前的HTML页面中的img标签如下：
<img src=”data:image/png;base64, [这里把上面的base64编码替换进来（包括左右的中括号）]”width=”30px” height=”1px” alt=”sea” />
然后保存，测试一下结果，发现图片已经嵌入到页面中了：
以上就是嵌入图片的方法，我们看到，其实就是将图片的数据嵌入到了页面中，使用这种方法会显著增加HTML文件的大小，如果不是非常小的图片或者十分有必要这么做的情况下，我们尽量不要使用这种方式。
我们最后看一下“data:image/png;base64,”这个写法，这句表明我们嵌入的是png格式的image文件，使用的是base64编码，那么你肯定猜到了，还有很多别的资源也能够被这样嵌入到页面中，具体格式在下面列出：
