[O] extra paragraph in image export?

[Matt Price]

with org-html-html5-fancy is non-nil, images are exported with something like this code:

<figure>
<p><img src="" href="https://imgs.xkcd.com/comics/proof_2x.png">https://imgs.xkcd.com/comics/proof_2x.png" alt="proof_2x.png" class="fragment (appear) visible current-fragment" data-fragment-index="0"></p>
</figure>

At least in ox-reveal, this makes it quite difficult to address images separately from text (e.g., to set the text-align property appropriately.  You can try this if you have ox-reveal installed with any simple image:
----------

* Test

[[https://imgs.xkcd.com/comics/proof_2x.png]]

--------

At least on my machine, the image won't be centered in the resultant slide, and it will be hard to construct CSS to fix the issue. 

Is there a strong reason to include the <p> tag? I've removed it from org-html--wrap-image and haven't noticed any ill effects so far, but haven't done much testing.
