In #50 the progressive image feature is explained.

The example image

https://images.weserv.nl/?url=upload.wikimedia.org/wikipedia/commons/e/e0/JPEG_example_JPG_RIP_050.jpg&il

works also when we serve the image from our server.

But when we use https://cdn.vrdoro.com/data/vrdoro/images/11/D2DA86F06A753397A10995708417CC49.jpeg as

https://images.weserv.nl/?url=cdn.vrdoro.com/data/vrdoro/images/11/D2DA86F06A753397A10995708417CC49.jpeg?il

throttling the network we see that it is not progressive.

What is wrong here?
