Where to upload files to access through browser?

I'm aware of being able to add files to the 'Public' folder and being able to access them through http://public.me.com/username, but where can I upload files just to access them directly without the iDisk interface? Lets say I want to upload some images to display on a forum or something?

I tried creating a quick website through iWeb and was hoping I could figure out where those files are added, but I don't even see those files when browsing my iDisk. I thought they would have been in the 'Sites' folder but guess not.

Oh, looks like those iWeb files are located in a folder called 'Web/Sites'. How creative...

So I'm not quite sure what the 'Sites' folder in the root is for.

I take it if we want to direct link anything, they need to go in the 'Web/Sites' folder?
