This is a Cartesian product that is subsequently LIMITed. Is that
intentional?

I don't fully understand the logic, but can't you just grab the
exact data you need in one query?
SELECT rnt.ID, pics.img_name
FROM Rentals rnt INNER JOIN pics ON rnt.ID = pics.rntID
WHERE featured = 1
ORDER BY RAND()
LIMIT 1
