If the ONLY “thing” you are doing remotely is the logo image for your site, then it makes little to no difference which approach you take.
On the other hand if your website will have many images, PDFs, zip downloads, and other things then having all that “stuff” directly uploaded to your server by you can be more convenient and result in a MUCH small project file. And you won’t have the potential problem of broken resource links.
As an example, I have a current course running. The RW project file is 18 Mb. If I put all my digital “stuff” on RW then the project file would be at least 1 Gb! And I’d have to be willing to trust RW (this is a non-Foundry issue) will handle all my resources nicely. And publishing the site will become a longer, more burdonsome, experience.
… so which way to go has little to do with your Nav bar, and much more to do with your overall situation. When I am putting all my “stuff” on the server it becomes more confusing if a few things are not done that way. Better to have a consistent approach: all resources OR all server upload. Hope this makes sense.
