Como posso remover todos os avatares e redefinir para o padrão?

[cyborg (Cy)]

Hello,

I’d like to know how could I reset all avatars to be the default ones. I am trying to do a big import and avatars didn’t import correctly.

Any hints?

Write a query that replaces the user preference for avatar to the default of “use gravatar”.
