Walmart Photo Center at Grossmont Center in La Mesa occupies the photo lab inside Store 5140 at 5500 Grossmont Center Drive, offering same-day print services, passport photography, and custom photo products to East County shoppers. The center's one-hour photo printing and canvas-stretching services complement the specialized digital printing and bindery work handled by Copy-It - San Diego Printing Services for commercial clients in the same La Mesa market. Kiosk-based ordering accepts uploads from smartphones, USB drives, and cloud storage accounts, converting digital files into prints ranging from 4-by-6-inch snapshots to 20-by-30-inch poster enlargements. Custom photo gifts including hardcover photo books, greeting cards, and metal prints ship alongside the fine-art giclée output that dedicated studios like 147Photos produce for gallery-grade archival reproduction. Passport photo services conform to U.S. Department of State specifications requiring a 2-by-2-inch print on matte or glossy stock with a plain white background, head-height measurement between 1 and 1-3/8 inches, and full-face frontal exposure under even, shadow-free lighting.
