For themes to override, create a plugin hook listening to 'entity:icon:url' and object 'user'.
In the hook return a different url.
To replace default user icons in a plugin one might create a hook:
function profile_usericon_hook($hook, $entity_type, $returnvalue, $params)
{
if ((!$returnvalue) && ($params['entity'] instanceof ElggUser))
{
// return your default graphic here.
}
}
And set it to priority 900 (lower priority than the code that displays a pretty icon for users but higher than the default object display code in entities.php)
