Teachers assigning projects and students creating them share the same frustration: how to present multiple visual elements cleanly without spending hours on layout. A photo grid is the answer.\n\nSchool project grid use cases: (1) Science fair — 2×3 grid showing hypothesis → experiment setup → step 1 → step 2 → results → conclusion, (2) History timeline — 1×4 horizontal strip with event photos in chronological order, (3) Book report — 2×2 showing cover, key scene illustration, character map, and theme visual, (4) Art portfolio — 2×2 or 3×3 showing multiple pieces for submission, (5) Geography project — 2×2 comparing four different regions or ecosystems.\n\nFor printing, export at 3000px (300 DPI for 10-inch prints). For digital submission (Google Classroom, Canva, PowerPoint), export at 1920px. Keep file under 10MB for most school platforms. MergeFrame works on school Chromebooks — no software installation needed. All processing is local, keeping student work private.
