How can I make sure that when people upload files, they always have a different name, so that they don't wipe off the old file? Is this a good way: 
#$imagename is name of file
$num=0;
while(-e "$Data/$category/$imagename"){
$num++;
$imagename=$imagename$num;
}

My brain is starting to fizz. Please help, oh lovely fellow monks!
