An absolute path such as &quot; C:\homepage\graphics\picture.gif &quot; would no longer function on the provider server. Neither a server nor the computer of a reader needs to have a C: hard drive: operating systems such as Unix or MacOS do not recognise drive letters, and even if the folder homepage\graphics existed, your picture would not be available. It is better to use relative addressing for file links.
绝对路径 (如“C:\homepage\graphics\picture.gif”) 在供应商的服务器上无法正常工作。无论是服务器还是读者的计算机都有可能不具备 C 硬盘驱动器：因为 Unix 或 MacOS 等操作系统不能识别驱动器号，而且即使存在文件夹 homepage\graphics，里面也可能没有您的图片。因此，对于文件链接，最好使用相对地址。
