The background image alignment on my blog should now work properly, staying “fixed” from the top until the window height becomes greater than the size of the image (and it’s offset), at which point it should align itself to the bottom. As with everything else, feel free to use the JavaScript, though I didn’t test it in IE. In a mixed note, IE has overtaken Firefox as the #1 browser in my stats, though it still pulls less than half the Mozilla variants (Epiphany/Galeon and Camino) combined.
I’m pretty sure it has to do with my recent comments on lefty political blogs pulling in readers from outside the Free Software community (which, by nature, is a Gecko– or KHTML-/WebCore-using audience).
