After having already loaded the full screen viewer (not the HTML 5 OS-level full screen, but just page filling overlay), shrinking the browser window fires off 4 http requests. Say the current window size requested 1280px width and I narrow the window to about 800px wide

* Current image at 1024px (XHR)
* Current image at 1024px (Image)
* Some image I previously viewed at 1024px (XHR)
* Some image I previously viewed at 1024px (Image)

Imho shrinking the window shouldn't fire off any http requests. The browser is good enough at scaling (especially with HiDPI in mind). Certainly not worth it when just adjusting the screen a little. But either way, if you really want to, just fetch one :)

Steps:
0. In Chrome (35; stable), 1440x900px Retina display, browser window maximised.
1. Open https://commons.wikimedia.org/wiki/Category:Carla_Bruni
2. Click "Nicolas Sarkozy and Carla (..) Obama.jpg".
3. Close it, and click "Michelle (..) G20 leaders tour.jpg".
4. Open Dev Tools (pop out), focus Network, clear current log.
5. Resize window to about half the width

Expected:

No network activity
