Nuno has good advice. Too many uneven wraps will cause the string to slip and too few wraps will also cause slippage.
I go around two or three full wraps on the
wound strings and three to four on plain strings. I saw a cool diagram in an ESP pamphlet I just read last night that showed a cool technique for plain strings.
Here's what it says:
1. Insert string into post leaving a little slack for winding
2. Wrap string around post (clockwise for bass side and counter-clockwise for treble side) and go under the string where it goes into the post
3. Pull the string tight over itself making a sort of knot or "hook" around the original string where it goes into the post
4. Tune to pitch, making sure the wraps wind neatly down the post.
I wish I could post the diagram - it is very obvious what they describe when you see the pic. Hope that helps.
edit - Your pic didn't show up the first time I read your post but now I see you showing the proper way of stringing (for me and many other forumites) for a TREMMED guitars but he was asking about
fixed bridge guitars. That still doesn't take away from your good advice
