Support for Images in Links

@zivester Since your fork has issues disabled, I'll try to ping you this way.

What a great component. Thank you both for your hard work! I'm circumventing the hassle with embedding local html files by using it.

Now what works out of the box:

Images

Links
[I'm an inline-style link](https://www.google.com)

But what about adding support for images inside of links?

What do you think?
