Hey Teak,
I think I can understand where your coming from. I have tried to make my website,
www.oxygraphics.candlehillfarms.net "Dummy" proof, although I don't think anyone here is a dummy. Maybe dropping the owner of the websites you are having trouble with an email will get you the help you need.
All my images come with the hex codes so all you have to do is plug and play so to speak, no more fumbling around looking for the right colors.
