Changes to ID card pics
Starting autumn 2025, we’re updating ID card pics as part of our LEGO® Account integration. New profile images—called avatars—will be available when you integrate your accounts, featuring a brand-new set of LEGO minifigures and backgrounds.

Previously, members could upload their own custom ID card picture. While you can’t upload your own photo anymore, you can download a previously uploaded custom ID card picture by clicking the “Download” button below your photo.

Leading up to LEGO Account integration, all ID card pics (including custom photos) will be deleted and replaced with a preset image. If you have a custom ID card pic you love, be sure to download it before it disappears!
