If the issue persists, we suggest to remove the images again and complete a local publish instead. Using the local publish only, transfer the files within your /assets/images/ folder.
To publish your web site locally with NetObjects do the following:
1) Open the web site within NetObjects Fusion.
2) Click the Publish Site button.
3) From the Publish window, select Local Publish.
4) Ensure that the "Published changed pages only" and click the Publish
button.
This will publish your web site to a local folder called "Local Publish".
Now you will need to transfer your files from your local computer to the
Netfirms web server. To do this follow these steps:
1) Open Filezilla or any other FTP software you may use.
2) Enter your connection information (please refer to your Welcome Letter for your account details) into the program and connect to the remote server.
NOTE: Please note that you should use Passive Mode for your ftp.
3) Within your FTP program, browse to the Local Publish folder on your hard
drive. If you used the default install directory the path the location
should be "C:NetObjects Fusion 7User SiteswebsitenameLocal Publish"
4) Within the web server side of your FTP software double click the www
folder.
5) Now drag the files from within the Local Publish folder over to the web
server side.
