web cam + php
Caros colegas
preciso montar um sistema que tire foto via webcam e cadastre informações referentes a foto. Consegui algo parecido em Clique aqui. Funciona perfeitamente. Ele salva as fotos em uma pasta. Preciso no entanto, criar algo que eu possa dar um nome a esta foto e informar data em que foi tirada. Pelo que entendi no tutorial, a foto é capturada em arquivo flash e guardada em uma variável, no entanto não tenho conhecimento suficiente para desenvolver tal aplicação. Se alguém puder me orientar ficaría grato.
