Ola pessoal!O php tem as seguintes funções:1 - Verifica se o mime-type do arquivo é de imagem if(!eregi("^image\/(pjpeg|jpeg|png|gif|bmp)$", $arquivo["type"])) { $erro[] = "Arquivo em formato inválido! A imagem deve ser jpg, jpeg, bmp, gif ou png. Envie outro arquivo"; }2 - // Faz o upload da imagemmove_uploaded_file($arquivo, $diretorio)e no asp, como seria?
