Right now I update the profile image every time the user comes back to
the site but obviously I'm getting broken images in the meantime.

I'll write a job to update these as JDG has mentioned but it certainly
is not ideal. The biggest problem has been the "Green Overlay" and
most recently "LiveStrong" overlay memes.

Not sure why Twitter doesn't just abstract the profile image with some
standard URL scheme.
