We discuss the contribution of Population III stars to the near-IR (NIR) cosmic infrared background (CIB) and its e®ect on spectra of high-z high- energy gamma-ray bursts (GRBs) and other sources. If Population III were massive stars, the claimed NIR CIB excess will be reproduced if only » 4 § 2% of all baryons went through these stars. Regardless of the precise amount of the NIR CIB from them, they likely left enough photons to provide a large optical depth for high-energy photons from distant GRBs. Observations of such GRBs are expected following the planned launch of NASA's GLAST mission. Detecting such damping in the spectra of high-z GRBs will then provide important information on the emissions from the Population III epoch and location of this cutoff may serve as an indicator of the GRB's redshift.
