Okay, so up to this point I've use Chrome browser 100% to get my site up, however today someone that was using IE went and said some of the images are just being shown as a red X. I told them to refresh but it remained. Concerned I opened IE and sure enough some of mine were doing it also. I am sure hoping this is just some dumb little thing to correct this, I dont know why some work just fine and others are just the X. Can anyone enlighten me?

Here is the site which isnt live yet.
