The article by Florian - "Storing Binary Data In A DB" has a glitch when used on W2K systems. This line...
$data = addslashes(fread(fopen($form_data, "r"), filesize($form_data)));
has to be more specific for W2K systems like...
$data = addslashes(fread(fopen($form_data, "rb"), filesize($form_data)));
credit TomTom with this finding. I just wanted to post it as a separate issue so it's easy to find and developers like myself whom have little time to pussyfoot with OS finickiness can make forward progress.
