The problem: users will be uploading images that will be stored in a database. I have no control over whether they are sending gifs, bmps, jpgs, etc., I need an accurate method of determining the mime type of the incoming file so I can serve the image correctly.

Using CGI.pm, I could try this: 

$type = $query->uploadInfo($filename)->{'Content-Type'};

However, browsers like to play "MIMEtype roulette", so this is not an optimal solution.

I've also found File::MMagic, but I have no idea how reliable this is. Has anyone used it before? If so, what are your impressions?

What I have works so far (we're only using jpegs, so that makes it easier), but once I let users at it, I need this to be as accurate as possible.

Any suggestions, or am I taking an entirely wrong approach to this?

Cheers,
Ovid
