dom, pager: cache images from network

With many limitations:

* slightly randomized expiry, so it's harder to fingerprint
* only images. so e.g. CSS is still left uncached
* it's per-buffer and non-persistent, so images are still redownloaded
  for every new page load

so it's more of an image sharing between placements than true caching.
