Featured Image thumbnail size – [listing]

Hi there,

I would like to ask your help regarding the featured image sizes.

I’m using a [listing] shortcode to show all of my property listing in one page. What I want is that I wanted to resize the thumbnail from 300×200 to a much more bigger size, is that possible?

It seems that it only allows the size of 300×200 for the featured image. I uploaded a bigger size and it resized the image to only 300×200 and the url of the image is (/my-image-300×200.jpg/).

I hope you can help me with this matter.

Thanks in advance!
