Whenever you want to send an image in a mail you usually attach it and that takes your precious time or by embed some HTML codes.
Gmail recently announced a new feature under Gmail Lab setting from which you can insert image by clicking a little image icon appear above the message typing box.
How to activate:
Go to Gmail setting > Labs > Insreting image application. Enable it.
When you open compose mail option there is an icon appear above the message typing box.
For inserting image just click on the image icon, then insert images in two ways: by uploading image files from your computer or providing image URLs.
If you send URL based images to Gmail users then they have to click on the “display image below” to see image because Gmail doesn’t show URL based images
