Well, the whole idea of this sticky is to tell people how to embed thumbnails in posts, not large images themselves, as large images aren't good for users on slow or mobile connections.
As it happens, Imgur does provide that ability, although it does clip the thumbnail (the large thumbnail option is pretty large!).
Simply upload the image
Once uploaded, click on the "Small Square" link beside the small image on the left.
The code boxes will change
Copy and paste the code provided in the "Linked Small Square for Message Boards" textbox.

Nice, I hadn't use them before.
