O interessante seria fazer isso com multi-threads, só que o php não é multi-thread, então você pode fazer desta maneira, criam um form com vários campos "file" e uma outra página php que recebe esse array de files e nesta página php você faz um loop chamando a sua classe de upload.
Tenta fazer ai e posta o resultado aqui.
