Recently Google resolved two major issues with Gmail. It is now possible to take a screenshot and paste it directly into an email message. It is also possible to use Gmail as standard email client that pops up when a user clicks on an email link on a webpage. Follow these steps:
- Download this application from Google
http://dl.google.com/tag/s/ap=<YOUR GOOGLE APPS DOMAIN>/googlewebapps/en/googleappsstandalonesetuptagged.exe
- This application will install three icons on your desktop
- When you start the email client it will ask to be your default client. Choose Yes.
- When you want to paste an image or screenshot just copy it and paste as you would in Outlook or any other email application. Voila. It works.
