When you renew your UK visa, you may need to have your photo taken again, even if your appearance has not changed much. The requirements are usually the same for the initial application: freshness (no older than a month), clarity, a white background,d, and compliance with the parameters. Some people try to upload an old photo, but the system may reject it if it was already used in a previous application. It is better to take a new picture in advance to avoid delays in processing.
