no way to turn it off via configuration
Thank you for the answer.
Maybe you could give me a hint, where I should search for it in the code to disable it myself?
By the way, wouldn't it be better to update the smf-avatar (and, optionally, the signatiture) by some kind of plugin on a separate CB-Tab and leave the CB-Userpic as it is originally?
I think, the idea behind the CB is to give some information about a user as a person, that means, also his photo.
