Adds an avatar upload field to user profiles if the current user has media permissions. Generates requested sizes on demand just like Gravatar! Simple and lightweight.
Just edit a user profile, and scroll down to the new “Avatar” field. The plug-in will take care of cropping and sizing!
Stores avatars in the “uploads” folder where all of your other media is kept
Has a simple, native interface
Fully supports Gravatar and default avatars if no local avatar is set for the user – but also allows you turn off Gravatar
Generates the requested avatar size on demand (and stores the new size for efficiency), so it looks great, just like Gravatar!
Let’s you decide whether lower privilege users (subscribers, contributors) can upload their own avatar
Enables rating of local avatars, just like Gravatar
