Default Avatar in vB 3.8.2

[محروم.كوم]

Hello,

I found something for previous vB versions, but not for this one (3.8.2).
I wish to set up a default avatar "no avatar" picture for registered users (guests, won't have a permission to post - therefore, there's no need to have a "guest" default avatar).

After registration, the user will have ("by default") this picture as his/her avatar.

The "no avatar"... avatar won't change, unless the registered user add his/her own avatar of pick one from the avatars "gallery".

I'm afraid, I'm not able to do this from the Usergroups section of my ACP.

Any suggestion, should be much appreciated,

Thank you in advance! __DEFINE_LIKE_SHARE__
