I don't know whether this will help, but the way I update my site is with FTP Commander. I stage the entire site on my hard disk (my website click here is 103 pages). Then I just copy the pages and images that have changed since the last update. It usually takes just a minute or two, so I make minor updates several times a week.
It is sometimes a bit complicated finding the right image to copy as NetObjects Fusion generates hundreds of auto generated images, but I open the local site in Opera, right click to get the image properties, then switch to FTP Commander to copy the appropriate image. Usually, I just have to copy a few html pages.
