Anything is possible; it just requires coding 
If you’re familiar with PHP and a bit of WordPress code, analyze /bp-core/bp-core-avatars.php for pointers.
Of course 
thanks for the direction though, I think I have an idea of what to do. Will post my results.
I think I need to correct myself in my first post, it seems that I was mistakenly calling wavatars gravatars. Oops! Wavatars are the randomly generated ones, right?
I had a revelation after realizing this though. I don’t want to stop people from getting their Gravatar if they have one, I just want to replace the Wavatars with my own images. So Im thinking I’m going to set the Default User Avatar to “Mystery Man”, then in the following line in /bp-core/bp-core-avatars.php
` if ( !defined( ‘BP_AVATAR_DEFAULT’ ) )
define( ‘BP_AVATAR_DEFAULT’, BP_PLUGIN_URL . ‘/bp-core/images/mystery-man.jpg’ );
if ( !defined( ‘BP_AVATAR_DEFAULT_THUMB’ ) )
define( ‘BP_AVATAR_DEFAULT_THUMB’, BP_PLUGIN_URL . ‘/bp-core/images/mystery-man-50.jpg’ );
}`
I was going to change images/mystery-man.jpg into `images/.jpg` and upload my 14 avatars (with filenames 1 through 14) into that images folder.
My issue is, if i was to do that, I’d somehow need to get the same image in the ‘-50’ version in the line below. And it also appears in bp-core-admin.php and bp-core-templatetags.php so I’m not sure what I’d do with them there. I was hoping this would be an easier solution. Any ideas?
Well I’m at a dead end here, would anyone like to give me another nudge in the right direction?
@javiermatosdes were you able to find a solution to this? Generating random gravatar for buddypress default profiles makes a lot of sense. Unfortunately, I am unable to bring that change in the buddypress default theme. Could you please help me with some advice on this?
Generate random gravatar? or random avatars via Settings > Discussions > Avatar and choose from Identicon, Wavatar, MonsterID, or Retro ?
Or check out https://wordpress.org/extend/plugins/bp-avatar-suggestions/
@mercime Thanks for your reply. I actually meant random avatar for the “members” of my buddypress site (not for those who leave comments!)
The option in Discussion Settings that you mentioned in your post is for posting comments. Ain’t they? Or please correct me if I am wrong.
My idea is to create different random ‘default’ avatars to new members who sign-up. Some members of our site do not change their avatars and because of that we have several mystery ‘men’ getting populated in Members Directory, Group Directory and widgets or wherever we are showing off members’ avatars. The site looks so odd with so many mystery’men’ avatars.
I hope you understood the problem. Do you still recommend me to try your ideas or the plugin? Thanks for your help.
