can't open the image, but have you tried removing, then shaking the image units and re-installing. Has cleared up individual colors backgrounding for me more than once.

What's that image supposed to look like? Try an example that we're familiar with, like a configuration page, or the demo print with the little yellow birdie. =^..^=
