[support] pictures reloaded theme header images

[Bert Van Kets]

Hi all.

I'm using Drupal 7.21, adaptive them 7.x-3.x and pictures reloaded theme 
7.x-3.0-rc1.
To accomodate my logo I set the header height to 120px instead of the 
default 88px. I increased the theme background images from 88px to 120px 
vertically. Then I set the height og the header images to 120 in the 
color.inc file.
No matter what I do, every time the theme is saved, the background 
images in the header have a dark bar at the bottom. This is due to the 
colorisation system of the theme. The background images are generated in 
the selected colors every time the theme is saved. The images are in the 
correct size - 120px heigh.

I can not find how these images are generated. If I understand how this 
is done I can find out why the dark bar is at the bottom of the images. 
I'm pretty sure it has something to do with the superfish menu 
background image not moving down with  the new header height.

What system is used the generate the theme images?

Thanks for any pointers.
