Existing deck, need to add a railing.

I have a rather large deck and need to add a railing to it.
It is trex decking with overhang built around the perimeter, it's picture framed.
My issue, my wife wants the railing mounted "through" the picture framing. Unfortunately in many spots where the 4x4 posts need to be will have nothing but a horizontal surface below to attach to.
Does anyone have any ideas? How to attach the 4x4 rail posts strongly?

It's anyone's guess without some pictures.
Most often done with 2 X blocking and through bolts.

Ideally, you would remove the picture framing all the way around the deck. Add 4x4 PT posts to the framing members having it boxed in and through bolted for stability. They re-install the decking around the posts. Purchase Trex post sleeves and caps to go over the 4x4 posts and then install railings and ballusters. Would have been easier if planned in the beginning, but hindsight is always 20/20.

That's the problem, on the sides I have verticals to thru bolt to, the fronts of the deck, however, it's basically solid underneath to nothing vertical to attach the 4x4's to :/

And yes about hindsight, the original plan was for steps around the perimeter, but unfortunately plans changed

DCA 6 shows how best to attach railing posts (they call them guard posts). Their details use through bolts combined with fabricated steel brackets at each post. If your deck's framing doesn't allow such, maybe you could use large (1/2"-dia.) lag bolts at those locations.

Remove the picture frame, cut your 4x4 into an "L" shape at the bottom. Lap the long side of the "L" against the rim joists and the full uncut portion of the 4x4 resting firmly on the joists. Through bolt the 4x4 through the rim joist and re-install your picture frame. This method is best presented if all the posts are installed in this manner. Not as clean a look, but sturdy and functional.

DCA page 19, figure 24, shows no 4x4's to be notched for guard attachment. 6x6's OK. http://www.awc.org/publications/DCA/DCA6/DCA6-12.pdf
