Apart from using Graph API as already mentioned above (https://graph.facebook.com/[PROFILE_ID]/picture), there are a couple more ways:
FlipTop has a service that pulls up all sorts of information on Facebook users, including direct CDN URLs (e.g. https://fbcdn-profile-a.akamaihd.net/hprofile-ak-snc4/275588_504804917_147319_n.jpg) of profile pictures. (Link to API documentation)
Cloudinary has a similar service, but with hosting thrown in the mix. They do require you to open an account, but it's free. Then you can use their CDN URL format to link to any picture like this: http://res.cloudinary.com/[YOUR_ACCOUNT]/image/facebook/[PROFILE_ID].jpg (Read more here)
