A basic example to generate gravatar using email address with Play Framework
Gravatar: An "avatar" is an image that represents you online—a little picture that appears next to your name when you interact with websites.
A Gravatar is a Globally Recognized Avatar. You upload it and create your profile just once, and then when you participate in any Gravatar-enabled site, your Gravatar image will automatically follow you there.
Gravatar images may be requested just like a normal image, using an IMG tag. To get an image specific to a user, you must first calculate their email hash.
The most basic image request URL looks like this:
http://www.gravatar.com/avatar/HASH
where HASH is replaced with the calculated hash for the specific email address you are requesting. For example:
http://www.gravatar.com/avatar/205e460b479e2e5b48aec07710c08d50
Size : By default, images are presented at 80px by 80px if no size parameter is supplied. You may request a specific image size, which will be dynamically delivered from Gravatar by using the s= or size= parameter and passing a single pixel dimension (since the images are square):
http://www.gravatar.com/avatar/205e460b479e2e5b48aec07710c08d50?s=200
Default Image : What happens when an email address has no matching Gravatar image? By default, this:
http://www.gravatar.com/avatar/00000000000000000000000000000000
