Since Gmail appeared in China, it has been widely acknowledged for its powerful functions from invitation to popularization and favored by many people. However, it seems that Gmail is not content with this, and it is constantly improving itself. This time, it has added three new functions which seem to have no practical value but are still worth affirming. These three new functions are: 1, Information about your login, Gmail will show where you have logged in and the last active time of your account. 2, Attach inline images. 3, View attached images as a slideshow.
