  Recently, it has been reported that photons can traverse naked singularities
in the Janis-Newman-Winicour and Born-Infeld spacetimes when these
singularities are appropriately regularized. In this paper, we investigate
observational signatures of hot spots orbiting these naked singularities, with
a focus on discerning them from black holes. In contrast to Schwarzschild black
holes, we unveil the presence of multiple additional image tracks within
critical curves in time integrated images capturing a complete orbit of hot
spots. Moreover, these new images manifest as a more pronounced second-highest
peak in temporal magnitudes when observed at low inclinations.
