Hi,
Just need an explanation.

When I use attach header from URL for a picture.

-H "Attach: https://upload.wikimedia.org/wikipedia/commons/thumb/3/38/Flower_July_2011-2_1_cropped.jpg/1200px-Flower_July_2011-2_1_cropped.jpg"

I receive a link to this picture.
Capture d’écran 2023-01-30 à 18 46 20

And when I attach a local picture receive picture preview
Capture d’écran 2023-01-30 à 18 47 21

Why don't have the same behavior? Why I can't see preview from URL?

Thanks

Embedding a preview from a foreign URL is not possible due to the browsers' cross-origin policies. Unless the other host allows us to embed the image, the image will not display. The only way around this is to upload the file to the ntfy webserver.

The Android app does not have this restriction. This is purely a browser restriction.
