png support in from_html plugin

support of png images used in img tags

How about if we modify addImage() to detect the format from the raw data? (it does already for data-uris)

I think it'd be matter of checking if the first four bytes matches with 0x89504e47

Check 0f3c2d0 - it's untested but i think it should work :)

hey, that's possible, but I just tried 0f3c2d0 which is not working as createDataURIFromElement (line 498) needs the format to convert the image to a data uri (i think)

Oops, wrongly recall fromHTML's images[] contains raw data while they are indeed IMG nodes :$

Well, i'm still thinking that should be added to the addImage plugin, so feel free to modify createDataURIFromElement by reusing the 'element.nodeName === 'IMG' block.

Btw, relying on the file extension isn't accurate as you can guess, but if we have to check that i'd rather use /\.png(?:[?#].*)?$/i.test(src)

8247a27 should do it.

yup, works great, just tested. thanks
