Have you checked your site offline? Do the images link then? It really doesn't sound like much but attention to detail in making sure the right images in the right image root directory are linked properly, unless you are not uploading to your server properly. I know as much as I've done it I still find I miss simple things like you are experiencing. Hope this helps.
The site runs fine offline. If I am watching it locally, it seems to be OK. The problem only occurs when I copy all of the content to the host. I have also checked to be sure that the images are in the correct folder and uploaded.
Here is one of the images that is definitely live, but is showing as unlinked/missing in the HTML5 version.
Also, here is the URL of the site for review
Got it! Apparently, it is the spaces in the URL (which are shown as %20). When the folder is moved/renamed, it worked fine.
