Is there a way to resize/reduce the thumbnail size being generated?

Hi,

I have managed to use the plugin without problem, however, the generated thumbnail size is way bigger (Dimensions: 640 by 360 pixels).

Is there a way to reduce the size of the generated thumbnail via settings? I have gone checking the plugin settings but did not see any option to set the thumbnail size before being generated.

Having to resize the thumbnail manually in the library is too much work if you have hundreds of images already.

Kindly guide.

Regards,
Eduard
