Slightly off topic, but can anyone elaborate on the legal handling of displaying the xkcd comics? As they are fetched directly from images.xkcd.com, and do not contain a "discussion", would it still be considered Fair Use, or have they made an agreement with Randall Munroe?

Their usage is noncommercial (no fee) and links through, so it satisfies CC BY-NC 2.5.
