Avatars don’t have a database entry. They live here:
/wp-content/uploads/avatars/[member_id]/[avatar file]
But there needs to be a thumb and a full-size, and you’ll need to change the file names.
And they may need to be jpg.
For example:
4f5664228829d-bpthumb.jpg
4f5664228829dauto-bpfull.jpg
I’m getting more familiar with how BP work. So here is a more specific way to ask my question. I need to hold all activity feed updates (site wide) until they can be approved by an administrator.
The 1.6 activity update is awesome for seeing all activity but it needs to be unpublished by default.
