The image will download the only issue is the server won't close the connection and keep sending data. Right Click > Save Image As save the image go to the save location there is a file called (lisa.jpg.crdownload) copy the file and rename it (lisa.jpg). you have the image.

I'm guessing the page keeps loading even after the connection is closed considering this error popping up in the console.

Even if we don't manually stop the reload, eventually it stops and the image breaks.

Can easily download the image on a Mac running macOS Monterey (V 12.0.1) using Safari Browser (V15.1).

"It was very effective"

Drag and drop the image to the desktop works on mac

Solution:
-add a draggable="false" to the image

if a large amount of connections are open the server seems to stop responding. Opening it up to a denial of service attack from any single desktop. for example opening 50k wget downloads in my terminal made the site stop responding.

A possible fix could be to limit same ip connections to a reasonable amount and/or raising the servers file descriptor limit should help

I'm able to save the picture by pressing and holding - save to images running iOS 15.0.2 (using Safari) without any issues.

Using wget, you can easily download the image in full quality, just hit Ctrl + C once the download has stalled.

I Currently using Version 96.0.1054.34 in Windows 11. I got a same problem using Postman (win32 10.0.22000 / x64) also. It may cause from getting image request.
