Looks like I won't be taking any pictures of a shuttle launch today. A low level fuel sensor failure has led NASA to scrub the launch. When I know more, you'll know more.
update: more here
update 2: NASA chief Mike Griffin says the launch will be delayed until at least Monday, July 18th... and that is if they can figure out the problem with the fuel sensor. NASA has until the 31st of July for this launch window; after that the next available window is from September 9th to 24th.
