[Hidden-tech] How do I find the pixel width of a picture?

[Shel Horowitz]

Hi, folks,

I have been told by my publisher that the photo of my book cover at
https://morganjames.box.com/s/i206k8xbasgko522uo0yonkrk11p3k4l
is 640 pixels wide. But the recipient, who wants to publish it in a
magazine, tells me it's not.

How do I determine the pixel width and fix it if it's incorrect? I do know
how to download it but I have no clue about how to determine or alter the
width.
