Again, a new Gmail lab feature! Allows you to insert images into a message body. You can upload and insert image files in your computer, or insert images by URLs. Great stuff!
To get it working:
- Enable the Inserting Images lab feature
- Update Mailplane to at least 2.0.9 or the latest 2.1 beta version
- Make sure you use "Rich text" in your message
- Click the "Insert Image" button...
