The message tells it to you:

In other words: the smallest side must by >=640
The message says w,h=640.. which to me meant that width could be something other than 640. Thanks for clearing it up.

Not all images are 640x640. Scaling is needed in order to use the plugin.
I didn't say 640x640 (it must not be a square image)
I said the smallest of width and height >= 640
You may use:
1000x640, 640x2000, 900x3000, 1920x1080 ...... and so on
any image having width>=640 and height>=640
