don't need an extension. go to the admin panel,
users and groups tab
manage users
choose anonymous user
from the drop down at the top /right choose avatar
check the box under the avatar that says delete image.
done.
just FYI, the only time a guest would be able to see an avatar is if they can post or can view profiles etc. the normal setting for those things is "no' for guests.
Guest can still see avatar (in my case photo) of the member who has uploaded a photo of him or herself.
With phpbb 2 I had a workaround to place "members with photo" in a certain group. https://www.phpbb.de/community/viewtopic.php?t=65401
So
"members with photo" can see other "members with photo"
"members without photo" can not see other "members with photo"
I was wrong in my post above. a guest can see the avatar of other users.
the drop down that I said to set to no will stop any guest from having an avatar, not from seeing an avatar.
the one brf said is the correct way to do it.
admin panel
users and groups
manage groups
click the settings link for the group you want
group avatar section
check the box for delete image ( under the no avatar image )
submit.
I have not tested this but it should do what you want.
