The images which are not loading are probably not where specified or either have a diferrent name than the one you write. Make sure the filenames respect Capital letters. Bizhat is a Linux server and thus is Case Sensitive.

For example the upper most picture (home.gif) is not showing. Maybe the filename is home.GIF or something lika that. Or even Home.GIF or Home.gif. Who knows? Make sure you rename the files to meet the filenames specified on the website.
