Im seeing in my wp-content/uploads/avatars folder that there are tons of avatars from when I created test users, but changed the avatars. So, i’m assuming that even if the user changes their avatar, the old file remains? That seems like a build up of unnecessary img files. Is there a way to discard the unused avatars, and only keep the users current full and thumb width image? Other than manually deleting them. It would be very troublesome trying to decipher which is being used in an live environment
Ive googled doing a cron job, but I'm not too familiar with the way it works. Any ideas?
