It's time that Easy Button started using image sprites. One http request is better than 50. Our pages could load faster, thus customers experience improved.
During an experiment with this, I found that changing from 50 image files to just one sprite image saved over half a second in download and rendering time for the page. This is a big deal in our short-attention-span world.
That's way Yahoo, Amazon, and all the big players use image sprites.
