Front Fork Bent After Crash
I don't think anyone can give you a valid answer from a photo.  Is there a fine crack there?  Who knows?  Certainly, no one can tell from a photo.  Are the forks bent unevenly or beyond their design specs, leading to handling problems?  Again, who knows?  

Personally, I would replace it without further ado.  It's steel, so although that does mean it can possibly be straightened, it also means it shouldn't be very expensive to replace.  A fork is an awfully safety-critical component to gamble with, so I would just replace it.  I want my forks in unquestionably perfect condition.  But if money is a serious constraint, I would, at an absolute minimum, have it inspected by a bike mechanic and take their advice.
