How to look at your photo stream from your iphone on the internet?

I'm not trying to trouble shoot or anything. I backed-up my iphone5 for basically the first time and have a lot of photos, already checked that I told my iphone to back-up stuff including my photos. I logged on to icloud and there's a button for finding my iphone, notes, calendar, contacts and like two other things but not photos. I don't even want to download them onto my computer. I just want to look at them in the cloud. Which they seem to be already there but I just don't know how to get them there. Internet seems to be no help because it only trouble shoots questions o mishaps.

There's a mechanism to sync PhotoStream photos to Windows PCs. I've used this and it works well. It adds a new folder to your PC, wherever your pictures are currently stored (e.g. The Pictures library, if on Windows 7).

Once they've been synced to the PC, you can just upload them using whatever software you'd normally use…
