Most of the photos are the work of university photographers Scott Corey and Kat Lawrence.
The exhibit, titled "Images of Mississippi," was drawn from thousands of photos Corey and Lawrence have taken in support of the university's Division of Agriculture, Forestry and Veterinary Medicine.
The display also includes winning entries from the 2010 4-H State Photography Competition.
It will be on exhibit until Nov. 30 and admission is free. The depot is open Monday to Friday from 8 a.m. to 5 p.m., and for three hours before kickoff on home football game days.
