Let me articulate the problem  I am having a little better. I have
applied a Custom Theme through FrontPage. It looks good on all of
the pages  except for the display.aspx, create.aspx, viewlsts.aspx...
etc... (all admin pages)

I understand that the gif  is a transparent gif and you can modify
the color  but if you do that you are taking away the transparency of
the the gif file. This Gif would then be applied to every site that
has the transparent gif of logo.gif in the CSS (every site by
default)

One possible solution  is to replace the logo.gif with the blank.gif
and that work fine for the admin pages but then you lose some of the
spacing that the logo.gif provides. I suppose I could modify the CSS
to acheive the necessary spacing. Let me know if anyone else has
any other angles on this problem.
