Not so fast! If you have the direct image link you can update the image even if the source post is gone. For example post #1039922 had the image http://68.media.tumblr.com/820e9d1aa6b4f349b9a09a5de17a4554/tumblr_og3u3kigom1vn7pt5o3_1280.png. The source post (http://the-mary-berry.tumblr.com/post/152718323953) is gone. But change 1280 to raw and you get http://68.media.tumblr.com/820e9d1aa6b4f349b9a09a5de17a4554/tumblr_og3u3kigom1vn7pt5o3_raw.png which is bigger than the old post so I uploaded it as post #1247649.

And don't forget

i thought that might work but i wasn't entirely sure so i didn't mention it.
