When I click the link and zoom in picture it does look sharp and pixel-perfect. Can you also zoom the picture?
Strange, for me using zoom does not zoom to original size but only to a slightly larger (but still unreadable) size.
But when I download the image to my computer, it is pixel-prefect indeed.
Perhaps it's something related to my (Firefox) browser? Or some Imgur behaviour I am not aware of?
Never mind, I'll take a look now.

So your screenshot comes from a computer display that has a resolution that exceeds mine. And Imgur doesn't seem to provide some 'actual size' view, so even 'zoom' remains restricted.
Even while off-topic, let's leave the posts concerning this here. They might be useful to others that (same as me) aren't aware of this.
