I understand the usual method for changing the default avatars is to place your new images in the default locations. This gets overwritten at time of upgrade and thus has to be done again (and again). If we could modify this path: /styles/default/xenforo/avatars, then pointing to new default avatars would be easy. The only path I see in style properties is styles/default which will affect all images. Is there a method of changing styles/default to change only default avatars?
