Very good solution. I was thinking of making a 1x1 in the background color, but tranparent is even better
As far as the link, who really cares...Its 1 pixel. No one is gonna find it unless they are looking really hard for it.
I have a question about this too. On this site it seems that you have two logos. One at each end of the screen beneath the header/menu type thing. Just curious how you pull that off. Or is that stuff just part of the header also, and you used the 1x1 trick?
