This will resolve even if there is no rawHTML. What if calling code always expects type and value for resolved nodes? Maybe we need to reject instead when there is no HTML?

	if (
	isRelativeUrl(node.url) &&
	fileType !== `gif` &&
	fileType !== `svg`
	) {
	const rawHTML = await generateImagesAndUpdateNode(
	node,
	resolve,
	inLink,
	overWrites
	)
	if (rawHTML) {
	// Replace the image or ref node with an inline HTML node.
	if (refNode) {
	node = refNode
	}
	node.type = `html`
	node.value = rawHTML
	}
	return resolve(node)

Is what we previously had. I didn't really look into the code besides that
