Oops, I thought that you had to write Scheme to do that. I see now that there's a handy dialog box, but that you're stuck with what it sets in the html.

So I went to look at that, and it's a bare img tag with no parameters other than the href. 

I guess you'll have to make your adjustments in your image. If you're starting from an svg, you could try passing the svg (with the appropriate sizes set) as your logo. Webkit renders svgs, and that should produce the best image quality. Otherwise edit your image to a smaller size, but keep the pixel dimensions the same (or resample higher) so that the dpi figure is higher; perhaps that will fix the pixellation.

Sorry to lead you down the wrong path.
