I've had a bit of a play and configured custom CSS to move the image preview, for Image posts, to the right, rather than centre. What I'd really like is for the preview to be smaller and up, inline with the header text, like the preview image from a Link post. In the attached example, I'd like the 4chan image text to appear similar to the whitehouse logo in the post below it. This would remove a lot of whitespace and condense the whole feed.

This is beyond my CSS ability. Is it even possible with custom CSS on the settings, or would it need a change to the backend?
