I had a request from "Jamie" who emailed and asked if I could track down the "montage type episode promo images (specific episodes not the season ones) - the photoshop ones that have cast and 'monsters' merged together" for Seasons 5 and 6. Strangely, they don't seem to produce these for every episode - just odd ones for some reason - with the latter half of Season 6 having the most montage images. Here are the ones I've managed to find - and as usual, right click and open in a new tab to view and download the large sizes.
5.2 - The Beast Below:
5.4 & 5.5 - The Time of Angels/Flesh & Stone:
6.3 - Curse of the Black Spot:
6.5 & 6.6 - The Rebel Flesh/The Almost People:
6.9 - Night Terrors:
6.10 - The Girl Who Waited:
6.11 - The God Complex:
6.12 - Closing Time:
6.13 - The Wedding of River Song:
I've emailed Jamie the large versions of these pics so please contact me should you require the larger versions that I have.
