Less chain noise?

Help - my chain line is doing my tits in. I've tried 2 different chainrings both 3/32 42T &44T, two different chains 3/32 & 1/8th, and two different sprockets both 15T 3/32.
Noise still persists, it sounds like when you get chain rub on a front deraileur i.e. same pitch suggesting its happening ever time a chain link passes. The noise is less pronounced when out of the saddle or pedalling hard. I've some pics of my chain line, can anybody see anything wrong?

sounds like your chainline is off, hard to tell from the photos though

are you sure it's dead straight?
