Optimum Gravatar Cache allows you to create a local cache with optimized copies of gravatars. The optimization is accomplished by resizing the avatars to the sizes used on your site, in addition to optimizing the images internally. Optimizations are performed to minimize the size of each avatar served by the plugin.
The plugin uses WordPress CRON to perform heavier tasks. Avatars are resized in the background. Avatars are optimized internally in the background. Except in certain cases where it is necessary to resize the avatars in the page request.
The plugin handles all your site’s gravatar as long as the wordpress get_avatar() function or buddypress bp_member_avatar() function is used. Works with plugins, themes, etc.
The plugin allows you to customize the avatar by default. This avatar is served whenever the user / visitor does not have a custom gravatar. This greatly reduces the number of requests made by your page, improving the user experience. Besides allowing to frame the avatar by default with the theme of your site.
The plugin, after being configured and activated, starts by serving gravatar for all. And it begins to create the cache dynamically in the background with the sizes being collected by the requests, as well as those configured on the plug-in page. When the avatar already exists in the cache, the plugin serves the avatar in cache. The plugin periodically checks to see if the user updated their gravatar on gravatar.com if yes is updated locally. This way, keeping an updated cache.
The plugin intends the following:
- Work with the gravatars locally, cache;
- Reduce the number of requests per page, thus reducing the total time required to load all files. This is achieved because most users do not have a custom gravatar, and for those, only one file needs to be downloaded;
- Optimize all avatars by reducing their size and transfer time again.
Please if you find any bugs of any kind please contact me so that I can solve it as soon as possible.

Help translate this plugin into your language
This plugin depends on the following PHP modules:
- php-gd or php-imagick (So that it can resize the avatars)
- php-curl (So that it can communicate with the gravatar using the same connection to update several avatars)
The plugin also depends on WordPress CRON to be able to solve the heaviest tasks in the background.

I have a great idea for your plugin!
Does the plugin work with Page Cache plugins?
Yes, the plugin works with the following list of page cache plugins:

Other plugins that offer a way to clear the cache for a given post / page as well as the entire cache will be added in the future.
Does the plugin support Cloudflare?
Yes, the plugin allows you to clear the Gravatars cache in Cloudflare.
Does it work well for new commenters?
Yes works well with new commenters. It is not necessary to be a registered user comment.
Do you periodically check to update the gravatars in case they are changed?
Yes, it is checked if the avatars have been updated on Gravatar.com and whenever they are updated there, they will be updated locally in the cache.
How can I add extra classes to Gravatars
Through the plugin configuration pages.
Go to the “Other Options” plugin configuration page and add the classes you need.
Using the wordpress get_avatar() function through themes or plugins.
<?php echo get_avatar ($id_or_email, $size, $default, $alt, array("class"=>"class1 class2")); ?>
Using the buddypress function bp_member_avatar() through themes or plugins
<?php bp_displayed_user_avatar (array ('type' => 'full', 'width' => 150, 'height' => 150, 'class' => 'class1 class2')); ?>
