**Motivations:**
- Diagnose why nostrimg.com returns 500 errors
- Verify if the code is causing the errors or if it's a server-side issue
- Log request and response details for troubleshooting
**Root causes:**
- Unknown: Could be code issue (wrong field name, headers, format) or server issue
- Need detailed logs to determine the cause
**Correctifs:**

- All headers (Content-Type, Accept, User-Agent, Authorization)
- Added detailed response logging for nostrimg.com:
- Status code, status message, response headers
- Body preview (500 chars), body length, HTML detection

**Correctifs:**
- Added HTML detection before JSON parsing
- Extract error message from HTML title or h1 tags when possible
- Provide clearer error message indicating HTML response instead of JSON
- Improved error logging with HTML body preview
