Can Invisalign fix a crooked smile? (photos)

After have reviewed your three photos, it seems to me that you are showing more gum tissues on your left side than your right side when you smile and your left teeth are shorter in length which both characteristics can make your smile look crooked.  This appearance may be caused by your upper lip on the left side goes up higher when you smile also.  Invisalign will correct crooked teeth, your teeth doesn't look that crooked to me, its your smile as a whole looks slight slanted.  Invisalign will not help your crooked smile.  I recommend you to visit a cosmetic dentist and have your smile evaluated.  I would suggest gingivaplasty (gum lift) and/or veneers for your back teeth (premolars area - buccal corridor) and if it's your left lips that goes up higher, then I'd use Botox to relax your upper left lip so when you smile, your upper left lip won't go up so high.  Lots of options, but Invisalign is not one.
