This error might be caused by:

 1. When you build your website with SiteBuilder, the pictures that you add take their source with path including your domain name. If the DNS servers of your domain name are not pointing to your server, that might cause your pictures to not correctly show.

 You can check if your domain name is correctly pointing from here:

 http://www.dsnstuff.com/

 2. Other issue causing your pictures to not display could be that the permissions of your files and folders are incorrect. Please check if the pictures that are not displayed have read permissions. If not, change them.

 3. If the pictures are in password protected directories, they will not display correctly again. Move them to non-password protected directory.

 4. If the pictures are not hosted where your site is, the other server could have HotLink protection.

 5. And finally if neither of the above helps, open your .htaccess file and check for the following rules:

 RewriteEngine on RewriteRule .*\.(jpg|jpeg|gif|png|bmp)$ - [F,NC]

 If there is such a line - comment it by putting # symbol at the beginning and save the file. This should fix the issue.
