What to include in a bug report
- The page URL and feature used.
- Browser and operating system.
- Source image dimensions, not the private image itself unless you choose to share it.
- Requested physical size and selected PPI.
- What you expected and what happened.
- For print-size problems, the measured length of the 100 mm verification line.
Privacy note
Do not send identity documents, medical images, private photographs or other sensitive files merely to demonstrate a size problem. A blank rectangle or synthetic test image is usually enough.
Advertising and rights requests
Use the same email for advertising questions, copyright notices, accessibility feedback and privacy requests. Describe the relevant page and the requested action clearly.
