Here’s a nice little improvement to Gmail, announced today on the official blog: to add an image into an email, simply drag and drop it there from your computer. You can then resize it and send it immediately.
This feature comes on the heels of a similar feature that let you drag and drop attachments into emails. The difference, however, is in the way images are displayed in the message; with this new feature, image is actually shown inline in the message (as opposed to being merely attached to it).
The feature currently works only in Google Chrome, but Google promises it will soon come to other browsers.
