Hash/checksum for an image?

[Brian Dunning <brian@xxxxxxxxxxxxxxxx>]

I want to make sure that a jpg uploaded by the user is unique. I was  
thinking about storing a hash code for each image in its MySQL record  
(got a db record for each uploaded image already). Is there an easy  
way to generate such a string?
