I will attack this one step at a time.
1. Your index.html file was saved as index._html (note the space) simply rename this index.html and that will fix this problem.
2. Your background image is not uploaded so it will not show it until you upload it.
3. The paths to your images are incorrect. For example on your background image on your index page you are calling it (by ../office51/gallery/www-back/purple.jpg) The easiest way to fix this would be to put the full url to the image. Thus manually edit that file in a text editor and replace that with (http://www.pgiftworld1.com/purple.jpg
) *assuming you uploaded the image to that location*
You will need to manually edit all files that are not using correct paths to fix these problems. Use what I said as a guideline, upload the necessary images, and you should be on your way. For other help you might look @ http://www.aota.net/FTP/index.php3
