Security Considerations & Verification
Ensure PNG header magic bytes (89 50 4E 47 0D 0A 1A 0A) are intact Check transparency alpha channel encoding if background renders black Files ending in .PNG should always be inspected for valid magic bytes to verify they match legitimate Images specifications.
