Disable images of unknown origin
Summary

- Malicious Content: Images may contain embedded malicious code that can exploit vulnerabilities in the recipient's software.
- Phishing Attempts: Images could be used in phishing attacks to deceive users by displaying misleading or malicious content.
- Privacy Concerns: Images may contain sensitive or personally identifiable information (PII) that could be used for privacy violations.
