[Resolvido] Upload de Arquivos?

Boa noite a todos!

Sou iniciante no ASP! Tenho um código de Upload para envio de arquivos (imagens) em JPG e GIF, que funcionam perfeitamente!!! Gostaria que o mesmo podesse upar arquivos com extensão .SWF e PNG, além dos que estão upando normalmente (JPG e GIF)!

O código que tenho encontra-se abaixo!

Se alguém poder me ajudar!!!! Eu agradeceria muito!! Pois, com o pouco conhecimento que tenho... tentei de tudo mas não obtive sucesso!!!

Um grande abraço a todos e obrigado!!
