I wrote this tool over the weekend to experiment with Google’s new Featured Images markup that allows the sender to designate a “featured image” of the email to be displayed when the recipient opens the Promotions tab in Grid View.

I thought I’d share it with all of you :)

You can paste any image in the link and see how Gmail renders it by sending a copy of it to your own Gmail account.
