Topic: How do I upload?

I know this is probably simple, but I've read the FAQ's and all the other posts in the forum, and couldn't find... or maybe understand the answer.
My site doesn't use ftp uploads. I decided to work around by using a link from there to my www.comcast.net personal pages. I developed a small simple viewer to practice. When I click on index.html it immediately opens in IE and works beautifully. I just can figure out how to upload it to either my site or my comcast.net personal pages. I'm using a mac with 10.4.6. I usually use "Fetch" to upload pictures. sad
