Well, I can skip binmode as the scripts are running on a Linux box. I'm not sure what you mean by issuing the correct Content-Type. Are you meaning that I need to do that if I serve it from the database? By saving the file directly to a Web-accessible directory, I thought the server would handle that when the users clicked on a link to the file.

Which raises another question: How do I determine the content-type of an uploaded file? Obviously it's not a simple case of checking the extension (since Macs don't use them).
