For security reasons, it's a good idea to load uploads from a different domain than the primary content is on. Currently the only easy way to do that is to do a server redirect, which causes problems with IE and wastes HTTP requests (see bug 628). It would be much more efficient to simply have global options to set the base URL for all images and other uploads. One option to toggle it on and off, another for the base domain and possible directory.
As far as I can see setting the full URL path in $wgUploadPath should be sufficient. 1.4 also has a prepended $wgUploadBaseUrl, but I'm not sure it's necessary.
As you can use $wgUploadBaseUrl, a new option isn't needed.
