Different loading screen

How it should go:

type in address, hit enter.
immediately, logo shows up in the center of the screen. it pulses a little bit.
load the page with the lowres background behind it,
then hide the logo and display the text, and focus the background all at once

issue:
because it loads everything at once, the page is blank for a bit too long. it should focus on loading the smaller images first, get those on the screen, and then worry about loading the rest of it
