This will not be enough, we will also have to expose `org-image--align'
and the alignment code:
(when align
(overlay-put
ov 'before-string
(propertize
" " 'face 'default
'display
(pcase align
("center" `(space :align-to (- center (0.5 . ,image))))
("right" `(space :align-to (- right ,image)))))))
I don't think we can expect third party packages to figure out and
reimplement Org's image alignment logic.
Considering this, it might be better to just split
`org-link-preview-file' into two public functions, where the "inside"
function accepts an image instead of a file.
