If the image is hosted via localhost, the only time it will work is if the email is opened on the local host of the individual user's machine. 如果图像是通过localhost托管的，那么唯一可行的方法是在个人用户的计算机的本地主机上打开电子邮件。 Local host is not able to be resolved on a different machine. 无法在其他计算机上解析本地主机。 (Computer, Phone, Tablet, etc.) （电脑，手机，平板电脑等）
If you wanted to make it work elsewhere, the server would have to be exposed with a URL/IP that could be resolved. 如果您想让它在其他地方工作，则必须使用可以解析的URL / IP公开服务器。
