How Gravatar Works?

The email id used on the gravatar account is converted to a string referred as hash. Let us take an example of an email id “” registered with gravatar site. This email is converted to a hash value, say “abcd”. Now you can get the gravatar picture just by using HTTP GET requests with an IMG tag as below:

<img src=”″ />

In the above code:

  • “abcd” is the calculated hash value
  • The corresponding email id is “”.
  • S=250 is used to resize the picture to 250px size.

When gravatar is enabled on your site, the platform will use the above method to fetch gravatar image related to an email id.

  • Generally gravatar images are not cached which will lead to slow page loading. You can see this problem when using Google PageSpeed Insights tool under “Leverage browser caching” section.
  • Services from is blocked in some of the countries, hence the small image can take long time and delay the page loading considerably, especially when the page has hundreds of comments.
