Thanks for the help guys.
My problem is that the featured image is being cropped to a certain aspect ratio. I want the image to fill the window width-wise but I want the height to be the natural height relative to 100% width. If that makes sense.
I want my images to scale to full width but not distort or crop, just scale width.
I mean I wouldn’t mind having a MAX height cutoff, but I don’t want a minimum. How can I solve this issue?
