I see images from "Regeneration", "Storm Front", "More Tribbles, More Troubles" and the "Trouble with Tribbles" as well the cover image from last year's Ships of the Line book, a D7 chasing a TOS shuttlecraft through an ice field (reminiscent of a recent New Voyages episode), a Borg cube attacking Voyager, a TNG shuttlecraft, TOS Enterprise in spacedock, a Dominion War battle and a battle-damaged Enterprise NX-01. I can’t figure what the remaining two are.
Amazon also have a cover up, though that appears to be half of one of the images from last year's calendar:
The calendar should be shops next month.
