For the cases where images are disabled or with a 404 error wouldn't

background: url(image.png);

do the same? Why have the red background in the first place?

What actually happens when the image format is not supported? Would the 
result be similar to what happens with IE6 and transparent png that 
shows a silver background?

I have forgotten to ask this previously. What is Issue-5?
