Sometimes handing your site over to clients or when you run a site with multiple users if can be a pain to explain how your 
users can create their own profile picture for comments or any other custom functionality that uses the get_avatar() function.
Before they would have to create a global Gravatar account which is fine if that’s what you want however, with this plugin there 
is no need to rely on your users having a Gravatar account.
This plugin will allow the users on your WordPress site to upload their own Profile Picture through the Media Library either by Uploading a new file or choosing one from the Media Library.

Tismy User Profile Upload

Upload your own user profile picture rather than falling back to the default or having your users create a Gravatar account.
