Does anyone know of a lightbox-style plug-in that will work with org-mode
HTML export that will automatically, on click, expand images to fill the
screen,  i.e. one doesn't require me to manually add an "href" and
"rel=lightbox" manually to each image?

(Most lightbox-style plugins require you to not just include IMG tags, but
to wrap them in something like <a href="img/image-1.jpg" rel=lightbox></a>)

Alternatively, is there a way to direct org to automatically add href and
rel="lightbox" to all images on HTML export in a way that won't break LaTeX
export?

Thanks!
