Leaking Driveshaft...HELP!!!

If you look at the second pic you can see the fluid running from the bearing side of the yoke in two spots.Doesn't look wet on top or bottom of the tranny.Leads me to believe its coming through the yoke.I would look very close for a hair line crack.The fact that it dumped a few quarts out over night with out any warning could mean something went bad at once or it was in a bind sitting.
