On Demo, there is an example of carousel and feature-list for filtered contents service. But the context of the selected content is forced by a parameter to retrieve the image to show.
It works fine for "metadata" images but not for "explorer" images.
I think adding a method to the resolver component with a context parameter should be a good idea.

Temporary hack:
In template match="content", replace url param by:

<xsl:variable name="url"><xsl:value-of select="$file"/><xsl:if test="$type='metadata'">?contentId=<xsl:value-of select="@id"/></xsl:if></xsl:variable>
