1. My images will not load

2. If I browse my site like www.domain.com it's working, while domain.com does not.

Please check if you typed the full path to the image :

http://www.domain.com/images/img1.jpg

or

http://domain.com/images/img1.jpg

and change it to a relative path :

images/img1.jpg

You should also be careful with extensions. .jpg is not .JPG
