Execute on nested image nodes (for use of <img> inside container <div>)

[fartinmartin]

Say I want to create a gallery of images in my markdown body. I might nest some <img>s inside of a <div> or gatsby-transform-remark custom component (as in this codesandbox). Doing so will exclude my images from being processed by gatsby-remark-images-anywhere. Is it possible to for this plugin to access those <img> nodes and process them?

Ah yeah, this plugin is currently expecting only one image per node. It should be able to handle multiple image nodes!

The culprit is again this line, since I used Array.prototype.find, it only search for the first image node in the direct children.

It'll need to be rewritten so that it can search deeper & also return an array of results. This means these lines needs to be able to flatten array as well, probably with flatMap or something like that.

I'll take a stab at it when I have a bit more time later this month, but as always if you'd like to explore a PR I'm hugely appreciate it!!
