/image/uid throws an exception when the user doesn't exist

[BigSpaceships]

I specifically noticed this with resumes where when it tries to load a profile image for someone who I'm assuming has had their username changed or something there's an ldap error. It would probably make sense to check to see if the user exists or not or even just try catch it all and return a 404
