The links from Moin Zaman show test results that are outdated (from 2008). As of my thorough testing today Gmail does support displaying embedded images for both methods.

做自己的测试，您可以用下列方法之一内嵌嵌入图像发送电子邮件
To do your own testing, you can send email with inline embedded image using one of the following techniques
-
- 启用和使用谷歌实验室插入图片
- 粘贴图像到Email客户端如Outlook 2010
发送使用上述任何一个电子邮件到您的Gmail帐户，然后打开Gmail的Web客户端（即适用于任何浏览器）的电子邮件，并使用向下箭头旁边的回复按钮，选择显示原始选项。这将显示它是如何收到。
Send an email using one of the above to your Gmail account, then open the Email in Gmail Web Client (any browser that works) and use the Down-Arrow next to the Reply button to choose the Show Original option. This will show you how it is received.
我认为最好的做法是使用嵌入式图像作为附件的方法。
I think best practice is to use the embedded image as attachment method.
在我使用Gmail Web客户端的测试，如果我在不同大小的单个电子邮件发送30幅图像，有几个不会成功加载显示图像的容器而不是图像。如果出现这种情况，请尝试重新加载页面。
In my testing with Gmail Web Client, if I sent 30 images in a single email of different sizes, a few would not load successfully showing image container but not the image. If that happens, try reloading the page.
在我的测试（Windows 7）中...
In my testing (Windows 7)...
- 铬（最新的）需要几个重载的成功加载/显示所有30个图像
- 歌剧（最新）将无法成功显示所有30幅无论重载的数量
- 火狐（最新）一致显示所有30幅没有问题
- 的Internet Explorer 9（最新）一致显示所有30幅没有问题
- Safari浏览器（最新）一致显示所有30幅没有问题
