It’s working for me too but you might want to look into this dynamic created image (or the way it’s created, I don’t know how).
If I open the image straight in Chrome, its size is 1400 x 700.
However if I open it straight in Safari, it appears to be only 20×20. On top of that, when I try to save it to locally, it doesn’t do anything.
So would just start there.
