wp_count_attachments( string|string[] $mime_type = '' )

Count number of attachments for the mime type(s).


Description

If you set the optional mime_type parameter, then an array will still be returned, but will only have the item you are looking for. It does not give you the number of attachments that are children of a post. You can get that by counting the number of children that post has.
