No pics, but it's pretty easy to do.
You have two straps, left and right. The difference is they angle outward towards the side they belong on. So the right one angles outward towards the right. You should be able to tell the two apart if you lay them flat on the floor. Other than getting them on the correct side, attatching them is the same.
The bottom goes through the D-rings at the bottom of the ruck. There should be a web strap with a sewn-in loop on the bottom end of the pack strap. Stuff the loop through the D-ring and then thread the whole strap assembly through the web loop on the opposite side of where you entered the D-ring. Draw it up tight. It will probably be easier to do this if you separate the two halves of the straps by using the quick release in the middle, but you don't need to. If you do use the quick release, pay attention to how it goes together, and then only do one at a time so you have a sample of how it's supposed to be.
On the pack, near the top, on the part that goes against your back, you will find two metal rings. They are attatched to the pack by web strapping. This is where the top of the strap goes. On the top of the pack strap is a length of web strap and a buckle. Thread the web through the ring on the ruck, and then through the buckle.
If you separated the strap halves, just reassemble the straps. Quite frankly, don't ever touch those quick releases again. They are there so you can get out of the ruck quickly in an emergency (like falling in the water). If you use them to take your pack off you'll eventually wear them to the point that they won't hold and your straps will be separating on their own. Additionally, you'll be showing to the world that you are a novice, as pros don't use the things when they take off their ruck.
Instead use the strap adjustments by loosening the straps to take it off, then they'll be big and easy to put on and cinch up. You can always tell a newbie by them fumbling with their quick releases when they have to get their ruck on.
