# Why do some Panini simulator sites show broken sticker images?

Broken images occur when simulators pull historical checklist cards without CDN assets, or skip the weserv.nl proxy required to bypass FIFA Panini hotlink protection. Our simulator filters to 2026 cards with verified proxied large-image URLs. The official paninicollection.fifa.com CDN blocks direct browser hotlinks via Referer/CORS rules. All working sticker crops route through images.weserv.nl/?url=…&w=900&output=webp. Cards mapped from 2010–2022 LastSticker checklists use /logo.png placeholders and are excluded from pack pulls.
