Fix blog image to inherit width instead of 100%

[marlonkeating]

When our blog images are getting resized in Ghost for different containers (i.e. thumbnail for blog roll or feature image for a blog post) they don’t look correct and we don’t have a way to edit them.

Ghost uses responsive images and automatically resizes the images we input. We'd like to change the parameters so that the max image size is smaller than the template currently allows. We should be able to achieve this with the following rule:
.post-card-large .post-card-image {
width: inherit;
}
