Works fine with wget it just keeps hanging but if you CTRL+C it and open the file it'll look fine.
The trick is to have nginx never timeout and just indefinitely hang after the image is sent. The browser renders whatever image data it has received as soon as possible even though the request is never finished. However, when saving the image the browser never finalizes writing to the temp file so it thinks there is more data coming and never renames the temp file to the final file name.
