Petander,
I had same problem uploading pictures. I have uploaded same size pictures previously, but now, the same pictures wont load. I think that something has been done to site with data upload matters.
With Zombie and Kryptonite greens, Zombie is darker green. If either is over baked, they darken.
I have suspicions, that your oven may be swinging with temperatures well above set area.
It would be interesting to know what is alloy temperature when taking them out after baking?
