Common mistakes to avoid
- A selfie, filtered or cropped group photo — CSBC wants a proper passport-style image
- A photo older than 6 months
- Using constable specs for the BPSSC SI form — the SI portal uses different dimensions (about 200×230 px, 30–50 KB)
Pro tips
- Keep the face at 50–60% of the frame with both ears visible
- The same photo gets matched at document verification — keep copies of what you upload
- Applying for SI instead? That's BPSSC, not CSBC — check its notification for the smaller pixel spec
