Why aren’t my images showing on nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg  if I post the url from my website?

This is a killer feature of nostr.  They seem to be doing some sort of wrapping of the link. Started happening via their web app a few days ago. 

Am I doing something wrong? https://image.nostr.build/842e4a9a928c63018bc2b67df79e410d2300d3bec7428f98f2bdf3e0668ccdb8.jpg
