You gotta tap on it to open it, and then zoom in.

Yes, I've used nostr, maybe my client is broken or something
Same here. Very weird indeed. Normally when you click on it you can save & zoom. With this .jpg you can't. At least in Amethyst. All other .jpgs works fine btw..
If you do a copy text in Amethyst you can see the url of the jpg. All seems normal at first sight.....
Sounds client side then. I have no issue opening it and zooming in.
