Thomas, in photobucket, when you are in the folder of the pics you want to post here, hover over the pic you want, and 4 boxes will pop up at the bottom of the pic you are hovering over. I use the bottom box, it links a thumbnail small enough to keep the loading times here within reason. The thumbnail you link will be clickable to get to the full size pic on photobucket.
I keep my photobucket full size so details can be seen vs. sizing everything to 640 width(you do lose detail at 640).
Anyway, click the bottom box, it will confirm the link is copied, then just come here and right click and paste it.
Steve- you could always run the nocks deeper on the sides of the bow limbs to keep that string from popping out, think of it like a pin nock with a shallow back nock in the stone. All you may have to do there is make the notches in those arrowheads a bit deeper towards centerline. Those would make real cool nocks...
