It looks like the t.4cdn.org subdomain isn't used anymore and thumbnails and full images are both delivered through i.4cdn.org. This was a quick dirty fix made from Ctrl+F "t.4cdn" and trial and error, but it seems to work. Ignore commit b670c9a, this is the first time I've filed a pull request and I don't know how to clear that accidental one.
