Salve a tutto oggi Super Savio mi ha aiuto a cerca di fare un rand()
però non và perche mi combina tutto il css:
ecco il php, mi dite come è l'errore grazie 
Codice PHP:
<?php
/*
By using this script you will be able to upload as many files as you want.
The code will check if file existes, limited extensions, file size, file selected ..etc.
For Q. E-mail/MSN: m(at)maaking.com.
