there's a few free pic uploaders (although they all die after not enough people donate) but i don't think there's any free video uploaders... because vids are big.
if you have any friends with a site you can ask them to give you a little space on their site via ftp.
my friend at
www.jammm.com/www.pop69pop.com gave me like 30mb which i can use how i want.
