Images do not come through, so we don't see what you're seeing.
That said, I'd expect page faults to happen:
1> when indexing. Besides what you'd expect (new segments
written to disk), there's segment merging going on in
the background which has to read segments from disk
in order to merge.
2> when querying, any fields returned as part of a doc
that has stored=true docValues=false will require
a disk access to get the stored data.
