My iphone takes photos, automatically uploads them to the cloud in a cool way and then they arrive on my iPhoto without me having to do anything – that's excellent but is it also possible for me to view the photos online through a browser or similar? Apologies if this is a particularly easy question – my google-fu is failing me today…

iTunes uses iTunesHelper.app to detect if an iPhone has been plugged in. This app is usually started as a login item. Therefore you could check if iTunesHelper.app ist listed here: Preferences -> Users -> Login Items. If it's not listed you can drag it back as described here: https://discussions.apple.com/thread/2313998?start=0&tstart=0.
It appears that a cookie (probably X-APPLE-WEBAUTH-HSA-TRUST) is stored when you choose to trust the browser. Clearing cookies should essentially disable this functionality and require a 2FA code to log in again.
When you sign out of iCloud using the browser (Click your name in the top right corner and Sign Out), you are also presented with this dialog:
If you uncheck Remember me on this browser so I don't have to verify my identity next time. and sign out successfully, the browser will require a 2FA code the next time you log in.

Modern Answer (2016): This is a feature of iCloud Photo Library, that launched in 2015 (and was in beta in 2014). With the updates to Photo Stream/iCloud Photo Library, your photo library is now viewable on iCloud.com.
Original Answer (2012):
This feature is called Photo Stream, and at this point, there is no web version of it.
The previous iteration of iCloud, which was called Mobile Me, did have a gallery option, but did not have the direct upload integration like Photo Stream (you had to manually post images).
