Easy iWeb publisher - How can I make changes?

I recently published my iWeb site, not to .mac account but another server. I used easy iWeb publisher because I am a complete rookie at all this and it seemed like the easiest. It worked fine but now I want to make some changes to the site...How do I publish only my changes to the site, without having to re-upload the whole site?

Thanks in advance...I appreciate any help you can throw this way.

I should add- I want to make these changes using Easy iWeb Publisher...

Thanks guys....Yeah, I think cyberduck is a good one. I actually figured out how to make those changes on Easy Web pub. and Cyberduck...It was extremely simple. There was a little menu bar that i missed, once i clicked on it it gave me the option of only uploading files that had been changed within the site folder...easy as pie.

Apprecaite the replies.
