- requires the manage_attachments permission.
- load the ManageAttachments template.
- uses the Admin language file.
- uses the template layer 'manage_files' for showing the tab bar.
- calls a function based on the sub-action.
void ManageAttachmentSettings()
- show/change attachment settings.
- default sub action for the 'Attachments and Avatars' center.
- uses the 'attachments' sub template.
- called by index.php?action=admin;area=manageattachments;sa=attachements.
void ManageAvatarSettings()
- show/change avatar settings.
- called by index.php?action=admin;area=manageattachments;sa=avatars.

number of avatars, attachment space available).
void MoveAvatars()
- move avatars from or to the attachment directory.
- called from the maintenance screen by
?action=admin;area=manageattachments;sa=moveAvatars.
void RemoveAttachmentByAge()
- remove attachments older than a given age.
- called from the maintenance screen by
?action=admin;area=manageattachments;sa=byAge.
- optionally adds a certain text to the messages the attachments were
removed from.
void RemoveAttachmentBySize()
- remove attachments larger than a given size.
- called from the maintenance screen by
?action=admin;area=manageattachments;sa=bySize.
- optionally adds a certain text to the messages the attachments were
removed from.
void RemoveAttachment()

array removeAttachments(array condition, string query_type = '', bool return_affected_messages = false, bool autoThumbRemoval = true)
- removes attachments or avatars based on a given query condition.
- called by several remove avatar/attachment functions in this file.
- removes attachments based that match the $condition.
- allows query_types 'messages' and 'members', whichever is need by the
