The Official Gmail blog just made a brief post announcing a new Gmail feature. So this means that Gmail does not only allow you to drag an attachment from your desktop onto Gmail but images as well.
Basically the new Gmail feature combines two features to allow Gmail users to drag email attachments and images as well. And its pretty simple to use as well. All you need to do is to drag the image in, resize it before sending the email.
Incidentally, this new Gmail feature currently works for Google Chrome only. But Google promises to make this available to other browsers as well.
So, if you’re fond of attaching files and images to your email messages, you’d might found this new Gmail feature useful.
